This place is Troutdale's best kept secret! In a word "AMAZING"! Don't be fooled by the tiny size. Their food is wonderful. I've eaten here less than 5 times but me and my brother are on a first name basis! Pi (Pronounced pie) the waiter, is a premiere, polite gentleman who is exceedingly friendly. I've seen Pi walk customers out to their car just to meet and pet their waiting animal. If you are looking for an exquisite atmosphere this isn't your place. Its small but quaint. More importantly they have fantastic food. They do take-out very nicely in sturdy containers.

This place is not very big. We went for a late lunch and got seated right away. There's some outdoor tables. The sushi was really amazing. We will be back for more.

Best Sushi I've had in the PNW. Kids had California rolls that were some of the best California rolls we've tried. The Heart Attack roll may just be the best roll I've ever had, at least top 3. Do yourself a favor and stop here when you visit Multnomah Falls. Also try one of the little Guava candies on the way out.

It's a smaller venue than some restaurants, and I haven't dined in, but on a Friendsgiving evening with a kitchen too small to throw a feast? They helped! We had one of every special roll and thank goodness for good friends because every one was a banger. Personally I know just above bubkis about sushi, and here I don't have to. No bad options, very patient staff!

We are here for lunch for the first time, friends showed us this gem. Beautifully presented sushi rolls that tasted delicious. All the food we ordered was exceptional. Friendly, attentive staff.

I travel for work every time when I come to Oregon I visit this location the best sushi ever

The food was fantastic and extremely fresh. The service was fair for the food that we ordered. It's smaller, but don't let that scare you from this wonderful hole in the wall.

Amazing customer service, Even better Sushi. Definitely my first time but won’t be my last!

Pretty good sushi, tasty rolls and tempura. Would go again!

Some of the better sushi I have had. Flavorful and fresh, prepared in an aesthetically pleasing manner in a clean and stylish setting.

We have been coming here for years and it's absolutely wonderful! Food is delicious every time and the staff and owner know their customers by first name and remember their favorites to order. My 4 and 6 year old love the soup and sushi and my husband and I have any many different items and they are all really good and fresh. Highly recommend

Food was a 10, service was horrible. We got attacked by a bunch of bees outside and the staff watched as they flew all over our roll and when I asked them to replace it they didn’t and charged me full price. They also didn’t bring any water, utensils, or take our order within a reasonable amount of time. -Love Karen

Delicious Thai and sushi, i liked the sushi more than the tum yum soup.

Stopped in for a quick session of sushi before a concert at the Edgefield. The sushi was fresh and delicious. The service was great, really nice people. We will definitely make it back next time we go to a show!

I have been going here for over a decade. I’ve eaten at many other Thai resteraunts and Siam Sushi is the best one by far. Not only is their food absolutely AMAZING (pad Thai & fresh rolls + peanut sauce, curry, & sushi), the people that work there are just as amazing as the food they put out. There is no comparison to the food here & this place holds a special place in my heart, and stomach ❤️

BEST SERVICE EVER! food was delicious. Our server was amazing. If your in the area this restaurant is a great place for sushi and Thai options. Food was delicious served warm. Place is extremely clean and staff was extremely friendly.

By far the best sushi I’ve ever had. Me and my cousin come here a lot and it’s good every time. The hours are odd but at the end of the day the food is to good so who cares. I’d recommend The sushi and chicken curry under the lunch/dinner specials. So good.

Stopped in on our way to Multnomah Falls and realized we made the best decision of the day so far. Pai gave us excellent service and told us all the great things to do around town. Food was soo amazing and had the friendliest service! 👍👍

My family loves Siam Sushi and Thai! It's a great option when different people want different things. The sushi is always fresh, the Thai dishes are great (though not spicy - if you want it spicy you definitely need to ask!). The prices are decent and the portions are generous. The staff is friendly and gets food out quickly. Great for sit-down or take out.

My husband and I are huge sushi lovers. Once we found this local business in the heart of down town Troutdale was a home run! The sushi was delicious and good portion sizes for the price. The service was wonderful and friendly. We found our new favorite sushi place to dine in.
