Kat, one of the things I LOVE about Universal/IOA/Citywalk is you don't have to make your dining decisions months in advance. Definitely check out menus, look at reviews, we'll all chat about our hits and misses, but if your group has an itch for Spanish or Italian or seafood or steaks, you can get really nice meals all over the Universal resort without having to commit months or weeks in advance.
I think you'll really enjoy the individual restaurants' uniqueness, individuality and creativity at Universal/IOA/CW.
