Absolutely ask for what you'd like to eat even if you don't see it on the menu. I asked for plain iceberg lettuce with a viniagrette one night when I didn't like anything on the menu. They gladly brought and offered it every night after if I wanted it. I didn't like desserts one night and asked for a just a small bowl of raspberries (there had been a single perfect one garnishing a dessert the previous night!) they went and asked the chef who had none left. But, after they restocked, the waitstaff either just brought or offered me a bowl of raspberries every night after that until they ran out again. And when they ran out, they remembered that I didn't like blueberries and brought out a bowl of strawberries and blackberries. They will do whatever they can to satisfy and please you, if you only let them know what your heart (or stomach) desires!
