Absolutely best Greek coffee and café frappé Greek style. In a sunny area, but still protected from the scorching sun of Athens, warehouse o2 offers a relaxing and very refined environment. Fair prices and very nice staff.

We popped in several times to this CO2 bar, sometimes for a quick espresso, sometimes for some food and mostly for some sparklings. We visited the other Warehouse units as well, but this was the best, with a really unique atmosphere, welcoming staff, just a street away from all the buzz. Tasted some local sparklings, good quality and also they offer more champagnes (franciacortas, proseccos, cremants) by the glass with generous pouring - which I think is not common on other places. Snacks and food was lovely too. Thank you for your kind hospitality; specially to the blond haired lady in the photo! If we ever return to the city, this will be the first spot to visit for sure. We both work in the wine industry, so we are picky - but this place had everything.

We enjoyed a mid day treat of wine and a Charcuterie board of local foods thanks to our friend Marina. Great wine and food pairing suggestions by our server. Amazing 🤩

Variety of sparkling wines. But if you don’t want sparkling wine, can have have it served only in a glass.

Very good and big selection of sparkling wine, Prosecco and champagne. Very nice breakfast and during the day small dishes like salads, oysters, bread with salmon and caviar. 50 gr of beluga caviar 80,—. At night special menue card. Very nice service and gay friendly. You’ll meet locals here. Only the street aside is very busy with cars. But just don’t look at it, look at the handsome waiters. 😉

Great variety of sparkling wines from all over, including Champagne and Greece, with a reasonable price.

I drank a very good sparkling Greek wine and had a nice fattush salad.

Great service, great wine - got some good recommendations for tasting greek sparkling wine 😁👍

Amazing selection of grower champagnes with great prices. the place in #Athens to enjoy fantastic bottles - great selection of growers to choose from including some of my favorite #biodynamic growers Champagne Marguet 18 Shaman delivers an incredible rosé 'assemblage using wines from Grand Crus Ambonnay and Bouzy. Majority Chardonnay which creates an incredible acidity while still highlighting delicious red fruits, incredible citrus notes, a beautiful body and complexity. Also paired perfectly with smoked salmon bruschetta with caviar and the most delicious sea bass ceviche with wakame salad, mango, kalamansi, chili oil

Fabulous spot for espresso and sparkling wine. The espresso I had was surprisingly one of the best I’ve ever had.

Fantastic wine list, and service was professional but friendly. Nice outdoor setting under a big tree, giving shade on hot days and keep your drinks cool!

Amazing cheese board! It was truly delicious. We had a couple of the sparkling greek wines which were fabulous. Friendly staff We would definitely go back.

The coffee was very good and the crossaints very fluffy and yummy try the chocolate one but I recommend be careful when your wearing white ;) Staff was super friendly and welcoming

Lovely wine bar focused on bubbly wines - they have some classic french champagne and cremant as well as some very local Greek wines. It’s a true challenge to accomodate a family group ranging from 25 to 65 and we all had a great time! We also loved the bruschettas with artichoke and cheese platters!

Nice after-shopping or prior-theater check point, where you can enjoy variety of sparkling wines with tasteful cheese plates, while sitting outdoor💖

We had a light lunch with wine here after visiting the Acropolis and the Acropolis Museum on 22/5/23. We had a nice sparkling rose and white Greek wine. My wife had the turkey and gouda sandwich.

Definitely an excellent choice if you are looking for a tasty and high quality coffee. As far as I could tell, they serve only drinks.

Fantastic wine bar that we found this evening. Our waiter had amazing knowledge of the wines on the menu and (although we didn’t eat) the food looked awesome. Highly recommend!

Had a wonderful evening here. The service was wonderfull, we got a great adive choosing our bottles and the waiter knew the all the details behind all vineyards. The selection of aperitifs was amazing.

Wish we could give more stars. This place was the last spot we wandered into in Athens. Only sparkling wines and all delicious. The service was amazing. We will be back here when we visit Athens!

Great coffee!! We have coffee here two days in a role since it is the best out of the five coffee cafes we have in central Athens!

Very good speciality coffee.

The young waiter that has served us was VERY knowledgable and VERY polite. We have been there a few times and we love it. He knows exactly what to bring us. I just describe what I like and he gets in a heartbeat. I wish more people were as astute as himself.

Great selection of (not only) sparkling wines from both Greece and renowned European countries. Small menu with nice snacks, very nice cheeses. Very competent and friendly somm!

Had a very good coffee here, on a hot day in Athens. The staff is lovely and the terrace has some trees that provide much needed shade.

A special secret spot in Athens.

Very nice wine and champagne bar, very good quality. Also the food was really nice Personel is very nice and professional. Nice and cozy place. I've had a really good experience and I can definitely recommend this place. I've good good advice on my choice of wine and was able to taste it.

Pleasant tucked in location, friendly and attentive staff, great selection of sparking wines, local as well as international, at decent prices, and tasty dishes. Great pit stop in downtown Athens. We were treated to a delicious custom made shot on the way out.

During the day, they serve great coffees in a cozy setting

Good food and very nice atmosphere, definitely a nice place to have drinks or dinner!

Cozy wine bar, great wine selection, delicious food and lovely staff

I didn’t know it was an exclusive sparkling wine bar, but the staff informed me as soon as I sat down. (They do use still wine for sangrias though). I went with the Moscato. Perfect summer glass of wine. Great place. Not too crowded or loud.

Fantastic wine bar on a beautiful corner, specializes in sparkling, but we enjoyed a great Greek Chardonnay as well. The Spritz was also on point.

I tried ceviche and Greek wine.... AMAZING. the best ceviche I've had. The wine was gorgeous too. I highly recommend it!!

Great coffee! The breakfast sandwich that I had was ok, not the best… but the coffee was worth it

Very good choice of wine bar in the centre of Athens!

Warehouse CO2 was a magical little spot the SO and I found after a bit of research between tours. Staff was extremely knowledgeable and friendly, and the bubbles were excellent! Cannot wait to visit again.

If you love wine it is the place to go. The staff is exceptional, highly skilled and friendly. Many different quality options both for sparkling wine and food.
