Some of the terms elude me as well. When in doubt, I order the number 7, and make sure it's not snails I'm ordering.
This restaurant seems fine to me. I just read the menu and some of the descriptions are rather intriguing even though I tend to be basic in my tastes. The paella dish stands out.
Eating out in my family is interesting as my wife's favorite is Italian, my younger son and I often prefer Chinese, and my older son lobbies for a steakhouse. My daughter, who's 9, is good with anything. We usually end up at the local bar/restaurant that has a pretty large menu, and they make outstanding wings. Plus, we always see friends and their families there too.
