Made reservation for Monday night. Absolutely recommended, the place was packed from 8pm and on.
We had 4 nights in Lisbon, all nights had great meals, but this one was our favorite. Not only because of the food, which was absolutely delicious, but because the ambience and food and wine combined was just wonderful - seriously delicious food in a very relaxed atmosphere.
We especially liked the deep fried green beans, the homemade canned tuna (sounds strange, but it was wonderful!), the lamb tagine and the fried scallops. The table next to us had the burgers, and if we had had more time in Lisbon we would have come back for that. Next time!
Do yourself a favor and make a reservation here!
