Much like a pizza, a hamburger is a culinary blank canvas; to just a single patty and a soft, chewy bun you can add nearly any ingredient and transform the burger into an all-new creation worthy of breakfast, lunch or dinner. On tonight's fourth and final episode of Best. Ever., your favorite Food Network chefs are exploring their picks for the Best. Burger. Ever., including meaty beauties stuffed with gooey cheese, classic favorites loaded with green chiles and bold, flavorful all-vegetable burgers.

Before you tune in tonight at 10|9c to learn where you can enjoy the stars' top finds, FN Dish wants to know: When it comes to between-the-bun specialties, what's the best burger you've ever had, and where did you eat it? Was it a juicy, no-frills burger from the diner, topped with cheddar and ketchup, or perhaps a gourmet-style presentation from a 5-star restaurant?  Leave a comment below, tell us on Food Network's Facebook page or Food Network's Google+ page, or tweet @FoodNetwork using #BestBurgerEver to tell us your local restaurant picks and share your version of the ultimate burger. FN Dish will round up your answers and reveal your top selections on Thursday.

Visit the Best. Ever. headquarters to find Food Network-approved restaurants near you, and keep coming back to FN Dish for more on pizza, burgers, barbecue and breakfast.
