I'd recommend Wolfgang Puck Express for your arrival day lunch, we've always found the food there "a cut above", and they bring the food to your table, so there's no tray "juggling".

They have great little pizzas and their bbq chicken quesadilla looks just like the one at the Puck Cafe (had it there and it was fabulous, haven't tried it at the Express so can't vouch for it 100%, just going by what I've seen in pictures).
Also, you can get a decent creme brulee for dessert on THE PLAN, or a lot of people have said the packaged cookies are good (and portable, if you don't have room for dessert right then and there).
Hope that helps! Good luck with your last minute dining decisions.
Planning is .5 of the fun, isn't it?
