deliciously saucy.. yum! that's the adjective i would use to best describe burger 21. they are a very creative and worthwhile addition to the tampa restaurant scene.
along with having arguably the best burgersin the tampa area, their real standout is the sauces! almost a dozen of those bad boys lined up and ready to flavor your burgers, 'dogs fries, and whatever else (shakes? fingers?).
my favorite is the toasted marshmallow, even better on sweet potato fries. the thai ketchup, which tastes like a blend of sweet chili sauce and good ol' heinz is a close second. the chipotle mayo is great on a burger, or even fries a la belgian style.
the shakes here, though a bit spendy, are awesome as well. the whole shebang is wrapped up in a clever diner style quick service format.
i have been to 3 different locations so far, and have never had a bad experience or a bad burger. note to mcdonalds, this is what the future of fast food looks like!
