Build your own tacos for three dollars! They are two dollars during happy hour! This place is called the "Happy Dog of tacos" for good reason--you check the ingredients you want on a list, including type of tortilla and side items, and it is promptly delivered to your table. A common complaint I noticed while skimming other reviews is that the food is not salty enough. What? My tacos were not lacking on any flavor, and the other people I have gone with (have been here four times total) all agree with me.
Excellent margaritas as well, with infused flavors such as pear, blood orange, and pomegranate. They are served in mason jars, which brings a little hipster class.
The only complaint I have is one of the nights, our server was not attentive and kind of rude. It wasn't busy that night. Maybe she was having an off day. I'll let it go for now.
When building your tacos, don't get TOO many ingredients. If your taco is soggy from piling on the sauces and salsas, you only have yourself to blame.
