We visited agostinhos at the recommendation of our taxi driver. Gosh were we impressed! I had the most delicious prawns I have ever eaten, freshly caught and cooked in a mind blowing sauce. We are all keen seafood and meat eaters so the opportunity to view the food before selecting off the menu was great (we had tiger prawns, Dover sole and squid). Nelson served us, and he was an absolute delight. Super attentive, helpful in terms of advising on the best dishes, and great wine recommendations too. The drinks are incredibly reasonably priced, and the food is also very affordable considering what you're getting. Having enjoyed the lunch so much, we returned the following evening for dinner. We tried more from the menu including sardines, fillet steak and the meat kebab, and were just as impressed as we had been the first time. In this area of Portugal there's great fresh seafood in many restaurants, but this one still managed to stand out for us. As someone who has eaten fresh seafood all over the world and ordered more prawn dishes than I can count, I can firmly say that the tiger prawns (the large ones) were the best I have ever eaten. We will certainly be making sure to return to agostinhos next time we are in the area!
