The last couple months have led me on a quest to find the best burger in the Fort Bragg area. I ate heaps of burgers, but two easily rose to the top of the pile.
Fort Bragg Steakhouse is located in a dumpy building and has unremarkable decor, but the service is quick and friendly and the burgers are tasty. I recommend you go at lunch for the burger special. For $7 you get a tasty patty with bacon and cheese, and fries, onion rings or a salad. This is by far the best value.
Mendo Burgers in neighboring Mendocino has the best burger with the loveliest ambiance, hands down. You can choose regular beef or organic beef, and the toppings are fresh and delicious. Fries are handcut and the banana milkshake has chunks of real banana. You can eat your meal in the adjoining dining room or outside in the garden. The owners' friendly dogs may be on-site to greet you.
North Coast Brewing Company deserves special mention for their delicious fries. The burger isn't bad either.
