Restaurant is up in the country, about 15 minutes drive from Albufeira and 30 minutes from Vilamoura, but well worth a visit. If you have a car, forget the rip off restaurants at Vilamoura Marina and Albufeira town and head to the country. You wont get steak egg and chips!! instead typical Portuguese meals. The monfish catapalana (26 eoros for 2) is the best I have had on the Algarve and I have been visiting the area every year for the past 20 years.
Tanks outside with lobster and crab plus an excellent wine shop inside selling Portuguese wines you wont find in supermarkets
I work on the principle of "Eat where the Portugues eat" and Mato a Vista`s diners are 95% Portuguese

This restaurant serves great, traditional Portuguese food. A lot of Portuguese families were eating there when we went, which is always a good sign! The service was efficient and reliable, and the food was great. Tasty vegetable soup, with a carefully balanced ham stock base made a great starter for all of us. We ate three different dishes between us as a main course - I had grilled salmon, my parents has a local dish called cataplana - it's cooked in a kind of small wok, and is made from a fish, and shellfish, wrapped up in ham. The version my parents had was mostly made from monkfish, plus whelks, shrimps, and prawns. My brother and his friend had wild pig, roasted in large lumps, with an olive-oil based gravy. We all greatly enjoyed this restaurant, but found the portions very over-generous. If you decide to go to this restaurant, 3 main courses will easily serve 5 people. I strongly recommend this place. The cataplana dish I mentioned says it will serve two, but my parents between them only seemed to manage just over half of it. The total bill was about £48, and this included 3 starters, 5 main courses, and 2 bottles of wine. By Portuguese standards, not a cheap night out, but a lovely restaurant with good food, great house wine, and a lively atmosphere.
