The margaritas at Tony's Mexican Restaurant always seem to stir up an endless series of questions, including, "What the hell is this secret ingredient?" and "Where the hell did you put my car keys, you asshat!?" This family establishment never seems to be anything less than packed, and for good reason: It's one of the Heights's best-kept and most-cherished Tex-Mex secrets. Featuring an intense but tastefully balanced combination of lime, tequila and buzz, these 'ritas go perfectly with a bowl of queso. If you're lucky enough to get a table at dinner, order a pitcher and start your own investigation.
