One rule of thumb to live by: Never take a foodie out to lunch. That is, unless you're a gastronome yourself. Foodies are a particular set of people who love to eat, discuss and salivate over all things food. Let's be honest, foodies aren't always the best company for a down home barbeque or potluck dinner, but the best among them have impressive palates that can appreciate the simplest and most intricate flavors out there, whether it's a juicy hamburger or a plate of foie gras. So whether you're a foodie wishing to test your chops or a more plebian diner looking to expand your culinary horizons, dig in to the tantalizing trivia ahead on the Ultimate Foodie Quiz. No napkins required.
