Best Restaurants in Portsmouth, New Hampshire | Eater Boston

"From the team behind beloved vegetarian bistro Green Elephant, this Thai restaurant focuses on Isaan cuisine from Northeastern Thailand. Sample drunken noodles, crab fried rice, and Isaan beef tartare. You’ll find pops of New England cuisine in there as well, like the lobster coconut curry noodles." - Celina Colby

Take it from a local, this place is great! First off, the food is very flavorful and provides local twists on Thai classics. The drink menu is creative and delicious. The décor is comfortable and inviting and the staff is very friendly. We did find it expensive, but what isn't in Portsmouth? Bonus: The parking is plentiful and FREE!

1st time and won't be the last! Wonderful service from Elyse, and all staff were pleasant. Nice outside space with comfy seating, and a beautiful bar and dining room. Excellent drinks and food with delicious flavor made with fresh ingredients. We shared small plates: the spicy tuna tartare (not overly spiced, and they'll dial it down if you want), the shrimp/chicken dumplings, the Laab duck, and the Teppan grilled mixed vegetables. All perfectly cooked and presented. The drinks get equal attention and are a clear step above the usual bar offerings! The May Flowers, Ride Along, and Slippery Slope were delicious. Kudos to chef and staff!

If you're looking for good Thai food and a place to sit down and enjoy, this is the place. The Decor is as unique as the food. Every dish we had was decorated like it was an art piece. The food was so refreshing it was satisfying. The dine in experience was worth it. The staff were amazing. I definitely will be back to try more from the menu.

Satiate your Thai food cravings here! The evening that I visited was hot as hell during the day and their AC was not working...I didn't care, it added to the authenticity of the dinner. Excellent spicy thai food, excellent service...highly recommended!

Such a hidden gem! This place is so cool, the food is excellent and unique, the drinks are on point, and the vibes are great. I love that you can get a bunch of small shareable plates, we were really tempted to order everything on the menu! My favorites were definitely the moo ping skewer and garlic calamari. I also enjoyed the tuna tartare and laab duck. For dessert, we got the souffle cheesecake which was as beautiful as it was tasty (both!). We sat at the bar and I enjoyed the conversation with the bartender, I can't wait to come back here!

A great option for Thai food. The prices are high, but the atmosphere is very elevated. The food is delicious, although the portions are small. Overall, if you are looking for Thai food in a fancy place, I recommend coming here. If you only care about food quality, I recommend Nikki’s over this place.

We spent just under 3 hours here this afternoon catching up with a friend we had t seen in years. Food was delicious! Where most Thai places just dump out piles of noodles with unbalanced sauces, these dishes were thoughtful and well-executed. We will be back! Shared 4 appetizers, 3 entrees, and a dessert! Thanks for a memorable meal, we will be back!

I don’t usually write reviews but I felt compelled to after our experience at this lovely establishment. We stumbled across this place on accident and we are surely glad we did. We were met by kind, patient and knowledgeable service. The menu is intimate with flavorful options many of which could be gluten free! There were descriptions of each item which was helpful if you don’t know Thai cuisine. I wanted to try everything because all of the dishes sounded sooo good. When the food arrived (in a timely manner) the presentation, flavors and portions were just right! You can tell the chef cooks with his heart. Every bite is unique and flavorful! The dishes I tasted were even more elevated than those I’ve had in Thailand. We will definitely be back to sample the differently monthly specials. Thank you Five81*NE!
