Starring Rolls is wonderful - for lunch. They close for the day around 4 pm and often sell out of sandwiches by 2.
If you have park hoppers, you would open up all kinds of choices by taking the boat from HS to Epcot.
If you want to stay in HS, my best recommendation if the weather is nice is to walk down the street leading to ToT, RnR, & F!. There are a string of individual CS locations and one mass picnic seating area. Some groups of tables are under canopies and others are in the open. In effect, it's an open-air food court. One place has burgers, one has pizza and salad, one has ribs & chicken, one has turkey legs, etc. Between them all, everyone in your group should find something for dinner and then you all meet up in the seating area.
