for a meal, Wolfgang Puck Cafe, for sure. Lots of choices there, something for everyone, and everything we've had from there (and the Express version) has been tasty.
Planet Hollywood is fun to just pop in for a dessert or an appetizer & a coke. But food is not all that special (we'd call it basic bar & grill fare...but way over priced.) Biggest problem is the noise level in there. Not exactly a relaxing place to have a meal.
