Pastamore also has pizza and pasta for lunch/dinner. You walk up, order your food, pay, pick it up, and there are tables outside to sit down. There's a Starbucks above it. On the upper level of Citywalk is a quick pizza place that sells thru a window. You could probably order a Burger and Fries to go from Nascar Cafe. Then you could walk around Citywalk to find an outside table, or sit on the wall (steps) near the boat dock. Here's my menu page, write down the phone numbers of each restaurant, then call when you arrive. I'm sure they won't turn you away, just tip a couple bucks when you pick up your order.

The other idea for quick food is to order pizza from Flippers.
Scroll to the middle of this page for the Flippers menu and phone number to call.

They'll deliver to the onsite hotel, you meet the driver on the side of the valet, tip the driver a few bucks. Onsite hotels also have pizza, but some get peeved when the hotel adds a service charge, so there ya go.
