Have you looked into the restaurants at Universal's CityWalk? There are lots of fun themed restaurants (Latin Quarter, Bob Marley's, Margaritaville) that won't break the bank. I personally recommend Emeril's but I don't know if that's too far out of the budget.
Anyway, there's plenty to choose from and CityWalk itself is a fun distraction. DH & I often wander around & go in some shops to work off our dinner.
