to my knowledge, leon authentic mexican is currently the sole mexican food joint in the entirety of antipolo city. just do a google search- the nearest to appear would most likely be the ones along marcos hiway and ortigas ave. extension. very far from the city proper. with this, antipolo peeps need not to venture far for their mexican food fix. and for those not familiar with the cuisine, they can finally try it out.
note that leon isn't just your run-of-the-mill place that serves burrito willy-nilly and calls it a day. they have a carefully crafted menu that gives patrons a wide choice of legitimate mexican cuisine, complete with uncommon ingredients such as cumin and cilantro, that's similar to big guns in the industry like army navy, silantro and el chupacabra. despite being 'seemingly' dwarfed by these big companies, leon can proudly stand on its own, shoulder-to-shoulder with them when it comes to food and service quality.
categories of their dishes mainly comprise of burrito, california burrito, fried california burrito, quesadillas, asada burrito, breakfast burrito, naked burrito, tacos, sizzling fajitas, mexican rice platter, and chicken wings, with a whole lot of other choices in their 'others' category. each dish is priced around p170-300, and they're already good for sharing. but you'll probably have your order all to yourself if you really appreciate this type of food.
i was able to try most of their stuff, and what i can say is that you get your money's worth: pretty much mouth-watering deliciousness served in big portions in all of them! and the various sauces leon provides make them even more delectable.
while you're at it, top off your belly-filling meals with their authentic imported mexican beers. they currently have variants of modelo, pacifico clara and corona. they're pretty hard to come by so try them out when you can.
