I have been to Taco Local three times now and have been very pleased with the food each time. My favorite is the street tacos. The base of cojita cheese, tomato crema, cilantro, (and more) is an excellent combination of flavors for whatever protein you choose. As for picking a protein, I haven't had one I haven't liked.
The bomb burrito (as other reviewers have stated) is in fact huge. It's a good pick if you want a solid dinner and leftovers for lunch the next day. The flavor is top notch, but be prepared for a lot more vegetables than your typical burrito.
On my most recent visit we had great service. However, the two times before the service was dodgy. While it only slightly hinders your dining experience in my opinion it knocks the restaurant out of the running for 5 star status.
