Went here with my two teenage daughters for dinner, and we all agreed it was the best of the four meals we had in the area during our short break. At tea-time the waiters from the various restaurants clustered around the beach-front here can be a bit over-bearing as they look to pull in trade: at Cais-velho they left us to peruse the menu in peace. This set the pattern for service throughout the meal; civilised, careful, gracious - although overall it was also rather slow, even though the restaurant was not completely full.
The setting is busy, right on the promenade above the beach, and hemmed in between and below other restaurants, though with the option to sit in or out front.
Food was good quality holiday fare; not haute-cuisine, but nicely cooked and presented. We had starters of octopus salad, tomato soup (no.1 said it was a bit watery), and prawns. The salad was a good size. No.1's main of Sea Bass came unfllleted, but the waiter offered the option of filleting it - not the most elegant or effective knife-work I've seen, but he more or less did the job. My paella (Algarve Rice) was gargantuan - no.1 thought the rice a bit dry, but I thought it was spot-on for a paella dish - with plenty of varied sea-food, though maybe a bit more seasoning required (I guess you can always add your own - you can't take it away if there's too much to start with). Sweets were excellent - not the more typical 'out of the wrapper' variety: no1 had a sundae; I had an almond cake, tasty but slightly dry; no2 had a selection of sorbets which were up there with the best I've ever tasted - the mandarin in particular. With soft drinks the bill - when it finally arrived - came in at under €90. Good value.
