The décor is simple, you would hardly believe you were in a Thai restaurant, but the food was good, I ordered prawn spring rolls which were delicious, and my husband ordered Thai fish cakes, which were not so good. We both ordered Thai green curry, mine with Pork, his with chicken, rice, a bottle of wine and a litre of... More

The ambience is nice. Ordered two different curry dishes, which both did not come really warm. Taste was adapted, not real Thai as one would expect. Dessert with pineapple - really forgettable. Will not return.

This is a small restaurant that was just 50 meter from our hotel. It is small restaurant that you can walk right by. You have to go up a flight of stairs. Friendly welcoming staff. I ordered two appetizers (spring rolls, satay) and chicken fried rice (big serving that I could have shared with others). Everyone ordered something different. We... More

Overall the experience was good! The dishes took the normal time for a restaurant in spite of the amount of groups on that day. I had the rice with chicken which comes in half of a pineapple! The portion was quite generous so, in my opinion, it could be shared with someone else. It was delicious and I will come... More

In a celebration day, the choice fell on this restaurant. The atmosphere is typical, the local spacious and the service is excellent. The food is very tasty (and spicy) and both, I and my partner, we were many satisfied . Recommend this tasty experience.

Always happy to enjoy the 6€ lunch menu here. My recent visit included trying the Chicken w/ Cashew nut dish. The portion was healthy and the ingredients were delicious. Casual atmosphere and a constant flux of custom trying to get in before the deal ends at 3pm.

The place is intimate with a casual ambience. I ordered the Tom Yum Goong and the freshness of the prawns really illuminates the caliber of fresh sea food in Lisbon. I had the Portuguese wine (15% alc) a bottle for sixteen euros, couldn't finish so took the bottle back to the hostel. All in all a pleasant repast on my... More

I was surprised by the food with flavours that took me back to my trip to Thailand. The food was well prepared, specially the Crab and the Tom Yam soup.

I decided to stop for lunch while walking back to my hotel. I am glad I stopped here. $6 Euro lunch specials make this place a great deal; not to mention the fact that the portion was so much I could not finish. I definitely reccomend this quaint and friendly resturaunt.
