I would call it The Geek Den. The decor would be all geeky/ nerdy themed like Star Wars, Pokemon, Video Games, Harry Potter, Comics, Disney etc... The food would have clever names based on pop culture. The servers and staff could wear geeky/ nerdy pop culture t shirts. The food could be served on mock comic pages or newspaper conics. There would also be a geeky store and candy shop attached. Kinda like a geeky Cracker Barrel if you will.
