As others mentioned - it's like Subway or Chipotle. The food is a bit on the pricey side (maybe that's related to the new minimum wage law?) and it just didn't blow us away. It's not bad, but I wouldn't go out of my way to grab some of their Al Pastor - but at least they HAVE Al Pastor, while others usually just have carnitas.
They DO have a ghost pepper hot sauce that's pretty good, and u can buy it for $5 a bottle, which is probably the best value in the joint. If you buy any "specialty" hot sauces - you'll know that is a decent deal!
We'll try it again on a Tuesday when the tacos are a bit more reasonably priced.
