Maya
When the term 'tequileria' is included in the name of a restaurant, it's automatically deemed a place to spend a National Margarita Day. For an upscale Mexican experience on the Upper East Side, $7 margaritas all day are definitely a steal. Try any, or all, of their different flavors, ranging from the Yucatan, with habañero, blood orange, and a chile pasilla rim, to the Maya, with tamarind, lime, and a chile piquin rim. Drink up!
