I'm in DC regularly for business, and I find myself always on the lookout for good mexican food and margaritas. I've tried Oyamel, Mixtec, Rio Grande, and Austin Grill. Oyamel was good but it felt like they tried way too hard. Egg foam on a margarita? Come on...I'm from Texas. Mixtec was recommended as more authentic, which it was, but their food wasn't that good and their margaritas were undrinkable. Rio Grande and Austin Grill are uninspiring chain restaurants. I can find food that mediocre back home.
Surely there are other options? Isn't there someplace with a full bar (with good tequila options) that serves good, authentic Mexican food? Price isn't an issue. It can be nice and expensive, or it can be a dive. I just am hungry for high-quality, delicious Mexican food in a place where I can get a good margarita. Any ideas? Thanks.
