When I first came to Lisbon with my husband, friends recommended this restaurant to us. The food was absolutely amazing and the service was pleasantly informal but polite. The restaurant itself looks very nice and is owned by a young couple. The prices are more then reasonable and not something we are used to (In our country you pay at least 3 times as much).
We were surprised to see that downstairs there was a gallery. The owners told us they sometimes do workshops aswell. When we were there, there was a Japanese themed exhibition. Overall a great experience:) The food/atmosphere is great and it's fun to take a peek downstairs.
