There's no shame in frequenting a delicious sit-down chain -- unless opening wide enough for the Awesome Blossom causes your fake glasses/'stache to fall off, in which case, there's a lot of it. For Austin Grill grub without the risks of being caught there, check out The Austin Grill Food truck.
Representing an established brand's attempt to get in on the District's swelling food truck market, the Grill-mobile's slinging their familiarly cheesy eats from a supernova-bright, red 'n yellow rambler rocking a massive "Lone Star" on each side, thus finally proving that people from Texas can't count. Gorge-able eats include:
Burgers and Sandwiches: Their original burger's topped with jack cheese/ fajita onions/peppers, while their chicken sandwich's got jack / smoked bacon/ chipotle mayo, and is seasoned with their special "Austin marinade", presumably so named for the bulk of Steve's fans, who, like a marinade, mostly just sit around all day.
Burritos: Holler at a grilled chicken joint stuffed with black beans and smothered in ranchera sauce, or grab a red beans/ ancho chile sauce'd number brimming with tender skirt steak, which, even if it wore a pant suit to work, would still get treated like a piece of meat.
Wings: Available in normal and "Texas Sized" platters, these mesquite-grilled, ranch-accompanied suckers are dry-rubbed -- after finishing the Texas Sized one, you'll be lucky if you can get same.
And should Texas-sized wings and steak burritos not fully do the job, they've also got supplemental snacks like red beans, chips and salsa, and a homemade almonds/Ibarra chocolate-filled "Austin Brownie", which would also make for a cunning disguise, as there's way less chance of you losing your fake sash.
