I don't know why they display ungutted fish, the only thing that comes to my mind is that this is used as evidence of freshness. Ungutted fish goes bad much faster than gutted fish and maybe they do it on purpose so they can say "See, we don't gut our fish, it's so fresh and gets sold so fast that it doesn't have the time to go bad!" But maybe I'm just thinking too much and they are too lazy to gut and scale the fish in advance. :-)
The first dinner featured the seabream and the anchovies.
The anchovies were battered in flour and deep fried. Oh man, did these smell when they were being fried. I had to open all windows to increase air circulation. Anchovies and sardines are the most smelly fishes, but this doesn't make them less tasty.
The dinner involving vongole clams is described here.
