Chinese/Italian/etc. buffets are always good. if there's any around your area that is. if not, then yeh. Olive Garden ftw.
Get those 40$ meals that give you like..a few vegies and a chicken wing, mcdonalds kids meal size.. I've done that... never eat at the dinner places at Hilton hotels if your really hungry unless u have money to waste... although the breakfast buffet was amazing..
