I know it's just a quaint little mexican spot and, too often, the majority of the clientele seem determined to get (or keep) their drink on with diesel powered margaritas, but the food is really pretty solid and deserves some love (or at least some published love since it seems that there are actually quite a few fans on this board).
Just back from dinner with 2 friends and we all agreed that Tapatio definitely fills a niche--it covers the basic "ameri-mex" (probably another reason that it can be overrun with the unruly) but the menu includes a lot of what strikes me as carefully prepared homestyle dishes--as if you were living with your mexican granny.
Tonite's meal--shared guac with fresh chips and a nicely kicked up salsa; guisado de res (short ribs in salsa verde with potatoes, good corn tortillas, a little salad and my favorite rice and beans anywhere); carne asada (skirt steak with grilled onions, a cheese enchilada and rice/beans); and Revoltijo Ajijic (open face plantain topped with steak, onions, poblano peppers, mushrooms, and chihuahua cheese, served with rice, steamed vegetables, and pico de gallo). They also do a mean Michelada. Not your typical burrito house fare but not the frou frou of some spots either.
I haven't been to Los Nopales--we were going to check it out tonite until I saw the note on the website that they're closed for the week--so I don't know how they compare but it would seem that, perhaps, they might have some common ground. I'm just happy to have Tapatio in the neighborhood. For anyone in need, they also deliver.
