Tucked away in a tiny compartment in the middle of downtown, Hubcap Grill is maybe the easiest place in the world to drive by without even seeing. Yet vast and ample rewards await therein. The burgers, oh Lord, the burgers: The patties are hand-formed, never-frozen beef, and the buns are homemade artisan bread. The meat is thick and juicy, with just enough spice to enhance the flavor without masking it. Among the best is the Philly Cheese Steak Burger, which comes with both a beef patty and shredded, Philly-style beef. The Frito Pie Burger is amazing and deliciously crunchy. Hubcap's aptitude for excess — they feature both the Triple and the Quadruple Heart Clogger, the latter with chili and a grilled wiener — stops just short of becoming a total train wreck. All the ingredients mingle well, and have been assembled with more deliberation than the kind of "I dare you!" mentality that plagues some specialty burgers at inferior burgerias. They're ballsy, but they're knowledgeable too; where else could you find a Mediterranean-style Muffaletta Burger with homemade olive mix and Swiss cheese? Hubcap is a true Houston jewel.
