Food inspires passion. Just look at what happened to that Marie Antoinette lady when she got all creative with her cake. But few forms of grub inspire as much as the hamburger. She is, after all, a fickle mistress. Handled carelessly, the burger can be disastrous. But crafted by careful and practiced hands, it can be a downright transcendental experience.Junior knows this. And it's with equal respect for the art form and childlike curiosity that he toils away in the kitchen — aptly labeled "the lab" — of this Miami Springs upstart. He conjures Angus perfection one-third pound ($6.99), a half-pound ($7.99), or one pound ($10.99) at a time, and all on your choice of toasted whole-wheat or cornmeal-dusted white bun. Peruse the menu and try culinary concoctions such as "the outside is in," a juicy patty stuffed with bacon and cheddar. Or check out the mouthwatering Acosta, topped with black pepper aioli, Swiss cheese, and French onions, and accurately deemed a "foodgasm." Or there's the one-pound Fat Albert, topped with Swiss and cheddar, French onions, bacon, and barbecue sauce. We won't go into detail about exotic burgers such as the "hail Caesar," Tex-Mex, beef Stroganoff, and "Mexi-can" burgers — you'll have to find out for yourself. And you'll need to check back frequently, because Junior is always in the lab, working on his next delectable creation.
