Went there without reservation, and was promised a table in 15 minutes, but got one in 30. I do recommend that you get a reservation, I overheard some people waiting on their previous visit for an hour and a half.

The staff is friendly and they spoke good English.

The interior is more on the traditional and warm side with all the wood. Quite small tables, but it all works out since they are bringing dishes in iterations. If you can choose, don't sit next to the door, since they will be opening and closing all the time. Maybe more of an issue for the colder months. Or do sit there if you want more fresh air. There's also the area in the basement and a gallery. The basement seems cozy, didn't check the gallery.

The food was great.

I heard they make a great Francesinha, and since I have never tried it before, this was the place for it. The assorted meat inside was of great quality and the portion was huge. I also learned I didn't like this dish at all, but nothing to do with the restaurant, it was prepared very well. If you like the individual taste of your food, this one is not for you. If you like to eat a lot for an affordable price, and just have a bunch of food stacked, this is the one. If you want as many calories at once, again, it's for you. I will probably never order one again. I didn't have high hopes, but everyone said 'You have to try it'. Well for those of you who think this is a bad idea, it is. For those of you who like the idea of an excessive dish, go for it, this is the place to get it.

The rest of the food was also great. I loved the look of the bacalhau tartufo, the crispy crust was perfect. Cannot single out any of the dishes, they are all great.

The gist is - I would recommend this place, make sure to reserve, and enjoy great dishes.
