Self proclaimed "Delray's Best Burger" is a bold statement. Not that I live in the burger capital of the world but to say you have the Best Burger in my city takes "chutzpah." They aren't listed in the top 10 on Yelp & Urban Spoon so this could be a tough one...
First things first. They specialize in Cheese Steaks. Bring more money than you think. The menu is, "8 yrs old and hasn't been updated," according to the manager. Which has great prices that don't ring up the same so DON'T BE FOOLED.
You can order the burger anyway you like. No specialty burgers. Nothing fancy here. A Burger the way you want it. So it comes down to the quality of meat and being properly cooked.
Solid size burger. You can tell they hand make the patty. My burger was ordered Medium but came just a bit overdone. But what surprised me the most was the quality of the Bun and Chopped Red Onions. Yup. Not a solid round slab of onion. They chop them up and top the burger giving every bite a nice even topping throughout the burger. And the bun, a nice buttered grilled bun really kept the flavors together. Heavy on the Ketchup and Mayo but it blended well enough to not be sloppy. The bun really held this burger together.
If you can get passed the service and wait for it to be cooked, it's a burger worth trying.
