Fiamme' in downtown Naperville for wood-fire oven pizza, and Little Italian for the best damn delivery pizza in the area. Portillo's for a quick burger and dogs, but if you want to sit down and have a monster burger, go to Ted's Montana Grill in the Bolingbrook promenade. Also, Andy's frozen custard in Bolingbrook. Downtown Naperville isn't far depending where you're staying. Heaven on Seven for Cajun, and Catch 35 for seafood are solid places in DT Naperville.
