Having booked to stay at the hotel next door we were a "captive audience" (the time of our arrival & the inclement weather precluded us from looking farther afield for an eating place - which is regrettable & added to the misery!)
The staff were friendly enough but the quality of the food was well below what was expected from the menu prices.
We ordered clams "bulho pato" style (one of our favourite dishes) for starters. When it arrived we knew almost immediately that it was not right as the smell which arose from the dish was distinctly unpleasant. A brief taste of the contents confirmed the suspicion that the clams were certainly not fresh and had, indeed, gone "off".
The waiter took it away (and, it must be said, graciously apologized) and asked if we would like to have garlic prawns instead. We accepted that offer but asked for a single plate to share.
We were served 2 full plates but again, they were almost inedible having been double cooked (obviously pre-boiled and then fried in olive oil with garlic - resulting in the chewiest prawns imaginable. We gnawed our way through 3 or 4 and gave up and asked for the main course.
Despite a fairly extensive wine list, there were very limited choice of half bottles (375 ml) but one of the few on offer was the Douro wine "Evel" and so I ordered a half bottle of that.
The waiter appeared with a full (750 ml) bottle and explained that they didn't have any half bottles in stock but said that we would only be charged for half a bottle.
By the time that the main course arrived - fortunately an acceptably well cooked & prepared grilled sea bass, we had perhaps partaken of more than half the bottle of wine - to cleanse our mouths from the foul taste of the clams and the the prawns.
Needless to say, we got billed for the whole bottle and having drunk most of it, I couldn't really complain - although a classier restaurant would have offered it for free given our disastrous meal - but there again, a classier restaurant would not have served up such poor food.
