This is a neat little eatery with tasty local food. The kitchen is right next to the eating area so what you see is what you get. It was empty when we arrived but filled quickly with locals which is always a good sign. Prices are very reasonable. Do not go here if after an upmarket feast. This is earthy, good, well-cooked local food. We found the service to be attentive and very friendly so not sure what some grumpy reviewers are no about quite frankly!

We decided to go to lunch at the last moment (lunchtime ends at 15:00) without reservation. The waitress seemed to be hands full since there were lots of customers still waiting their food but she waved us in. We ate grilled sardines and steak (of veal) and shared half bottle of red wine and sparkling water. The food was delicious and the place is very local and authentic although I think it can be full of tourists sometimes because of good reviews here in Tripadvisor and on travel books. Don't expect to get much service in English, for us it was a good chance to practice our Portuguese.

We were recommended to come to Ze Neto. Service was efficient but no fun. Small Portugese restaurant.
Food, we thought was very average, perhaps we were unlucky as others had dishes that looked better. We are judging based on our experience and wouldn't come here again.

(Incidentally we found in general in Portugal that the Portuguese Restaurants were empty-ish while the Italian restaurants were packed.)
