Main Street is quite depressed with many store fronts closed. Karen’s appears to be a bright spot. This is a diner, not fine dining (I do not believe such exists in the town). Staff are pleasant. The French fries were hot and perfectly crisped. My lobster role was decent. Sodas and ice tea come in plastic bottles so they do not brew their own. So if you want some of the basics, I would recommend this place.

Our breakfasts were EXCELLENT. Biscuits and gravy was very tasty and the blueberry pancake was HUGE!! I'm glad we didn't order 2, we wouldn't have been able to eat it all. The last dish was eggs, ham, potatoes, and toast. The potatoes were cooked with onions and were delicious. Asked for the egg over medium and was cooked perfectly. We would definitely return for another meal!

Sorry, no food photos, just of area outside. Gobbled it up too quickly. Lovely diner. Pancake (one side order/ blueberry) was as big as my head. Was cooked to perfection. Gorgeous light golden brown crisp on outside, light and fluffy inside. Had the breakfast sandwich and homefries with grilked onions as well. Delicious! Waitress knew regular customers and their schedules of when they visit by heart. Great small town business where the locals flock.

Adorable local dinner. Fantastic breakfast, wife and I split the big breakfast so we could try everything and it was perfect. Blueberry pancake was made by a professional. Delicious. Great value.

Don't really care for this place

Friendly service. Food was excellent and very reasonably priced.

Very friendly staff, food was good. We found it expensive, especially with the exchange rate added in for what you get. They need to fix the dripping air conditioner over the entrance and maybe clean up their window sills, lots of dead flies. Deferred maintenance and cleanliness.

We had very good clam chowder and lobster bisque. Also shared a basket of fried paddock with french fries. It was all very good for a decent price.

The food is excellent. Service is great. Food comes out fast and exactly as described on menu. Since moving to area we have been multiple times.

Great food wonderful service , it’s a very cute and cozy place with home like food. A great place to enjoy the local hospitality with delicious food.

Typical small town breakfast restaurant layout with booths and tables. Excellent food and service. Nice view of park outside. The front entrance needs some repair to the walkway.

What a great local diner! Forget Tim bottoms and macca’s! Real,Fresh Food Here! HUGE Omelets! Great sausage gravy and biscuits and hot coffee ☕️ the place was packed! Can’t wait for lunch lobster 🦞 roll!

Great service and these nachos are to die for!!! I’m from TX and haven’t had great Mexican or even Tex-Mex since moving here and to find some amazing Nachos in such a small town threw me for a loop! I went back two days late for another go at them!

Best breakfast place for miles! Skip dunkin and feel at home here. The bar has a great atmosphere at night too.

Busy holiday weekend so the food was not 100%, but still good. Bacon was under done along w toast barely toasted. Service was 100%, though. Will definitely return.

Good people good food. Food was hot wet and lots of it

Yummy food

Good food and good service

Great breakfast and super service in a very busy place. Don't miss this place for a great breakfast!

Very very neighborhood bar but the food was absolutely excellent.

Stopped here for lunch, and had an amazing pastrami sandwich. Food was very good and the prices were reasonable. Nice place right next to the town square. Also has an adjoining bar, so if you want a drink you can just order one.

Nice local place, friendly owner Karen

Best burger and fish and chips in Calais

Outstanding service and food. Best beer battered fish and chips evah! ( That’s from the New Englander husband) I concur!! Can’t wait to visit again. Thank you

While over in Calais I decided to try Karen's Main Street Diner, I guess my expectations were too high based off what I read online. The Atmosphere was not relaxing at all, there was one woman that was more than loud talking about being roofer and grand kids, it was terrible the way she was going on, it was like she was drunk at 3 pm in the afternoon. I could not wait to just finish my so/so meal and get out. The lobster sandwich (which was rated one of the best) could not have been up against much, as it was actually about mediocre, I have tasted worst but also tasted much better. The service was slow, the gentleman that was serving gave the impression that he didn't want to be there as if we were a burden to be there. I will say that was my first and my only visit to this Diner as it was not very diner atmosphere like.

Homey atmosphere and delicious comfort foods.

Lobster roll with lattice chips and a beer. Our bartender was excellent. The food and folks made it all gell .

Staff is VERY friendly and attentive! Food is always delicious. Just a great cozy atmosphere for a small restaurant!

Best little diner in Washington county! Love coming here and having breakfast at the breakfast bar. The servers are good people and the food has always been great. Go here!

Great food with a price tag that will make your wallet happy!!!! Breakfast is ready all day long and they always have something good on their specials menu!! It’s a place that I have enjoyed returning to over and over again throughout the years and has become somewhat of a tradition for my family and I to look back on and remember each visit fondly!!! Check ‘em out and get in on the fun for your family!!!

Prices were appropriate. I had breakfast burrito which was excellent. The people were polite and friendly. I enjoyed my time there.

Had an awesome breakfast. Loved the diner feel. Great place to start any day trip down Route 1 or 9.

Karen’s was great. We always look for small diners with basic breakfast options to start the day while traveling. This one did not disappoint. Downtown Augusta was cute and hopping with folks out exercising. The food was great while we observed the activities. We had a selection of eggs, pancakes and breakfast meats and were so happy and filled. We followed up with a walk along the trail. Service was friendly and our server kept the coffee flowing.

Great place to eat or have a beer! Best Reubens and Lobster rolls Downeast!

was in town for 3 days and had breakfast all 3 days and kept coming back, friendly and awesome! Kept clean and bathrooms spotless. Love the OVERSIZED PANCAKES!!!!

Convenient location, great food and service!

It was really nice to be able to sit down and have breakfast again, finally after 10 weeks of social distancing

Love it down to earth people

A fun local place. Good honest food. Return a second time and they will recognize you. Go back for a third time and they will know who you are. Nothing fancy but great steaks and burgers. Strong drinks, reasonable prices.

Great breakfast at a fair price... Friendly service 🙂

We all enjoy a delicious breakfast every time we go! We make a yearly visit during our annual vacation to Wesley, ME because we like it so much.

Clara, our waitress was so sweet! ⚽️Food awesome. We had breakfast before heading back on the road. On vacation from Florida.

Just left with tummy full and it didnt break the bank. Great food and the waitress was very courteous and nice. Cant go wrong with breakfast!

A full bar and good food and a clean rustic environment. I would recommend this place for a quick bite and a drink. The menu is medium sized. Their late hours are only until 9 or 10 which is not very late for a bar. I can not comment on the breakfast but the nachos and/or taco salad was really good. This is basically the only place to get a mexican inspired food dish in the entire area, but it is NOT a Mexican restaurant.

This is our new go to place!! The lobster rolls are awesome as well as fish and chips! Real coconut shrimp. Everything we have tried has been great. Good beer selection too!

Food was great, coffee was good, timing was good too. Robin was our waitress and she took good care of us. Definitely coming again next time we're in town

Good sandwiches, fries and beer. Friendly staff. Affordable.

Friendly staff, good good, great value.

Good service. Good food

Enjoyed the old cars

This place is awesome. Great service. Relaxed atmosphere. Good food. We had stuffed mushrooms, fried green beans, homemade potato chips, and a cheeseburger. Highly recommend!

Kinda decided on the five star before I even got my food, the server here, Brittani, is exceptional. She's very attentive and detail-oriented and I was impressed well before I watched her gingerly and delicately support-walk an elderly woman to her table. She recommended the fried dill pickles- a personal favorite- as an appetizer and even though I haven't looked at my to-go entree I'm more than convinced the appetizer earned five stars and it was hard to leave some for the people back home. It isn't doing anything fancy, but it's doing something reliably and well and delivers exactly what you hope for (even if it is spears, which is odd- but I promise they make it work). Atmosphere is solid, I came at a good time, it may crowd during a rush but things were calm and pleasant for the duration of my brief stay.
