El Cangrejo Loco, Port Olimpic, Barcelona

The two-level, sprawling Crazy Crab is more upmarket than many of the restaurants clustered down on this quay. To start, there is the usual selection of tapas, but weighted heavily towards seafood. For a main course, make sure you try one of the baked fish dishes, which come in very large portions of succulent, filleted white flesh. Near perfect, except it can be seasoned a little heavily for some tastes. If it is a weekday and you don't want to go a la carte, for 22 euros before tax, you can choose two starters, one main course and a desert from a surprisingly broad menu. There is also an extensive wine list, which includes a dozen cavas and a dozen champagnes (the latter starting at about 40 euros a bottle). The decor isn't very imaginative, but the harbour views and the ultra-fresh seafood more than compensate. 8/10
