Wish I could help you more (I lived in Reno almost 10 years ago), but a definite given is the old Nugget Diner in the back of the (I believe) Golden Nugget Casino in downtown Reno (not to be confused with John Ascuaga’s Nugget in Sparks). the Awful Awful Burger is legendary. Kind of seems like Reno is underrepresented on this site… maybe you could explore and post a report when you get there?
