We visited Taco Chelo last week and ordered a few of the pork tacos and barbacoa tacos. Barbacoa, albeit the meat was cold, had good flavor. Pork was also good, but overall it's not a meal I would find myself craving. Salsas were great, and the margarita was excellent.
With all the hype, design, and work to have this place open in our neighborhood, I expected more on the menu. You have $3.50 tacos, chips/salsa, and a couple other appetizer type foods that could rival a food truck - not a full service restaurant.
I can see us returning for happy hour and potentially a pre-dinner sort of situation. If I want to have a real (full) meal, I've got a list of other places we can go visit for that.
