Americans are use to burger and fries... as Mexicans are use to tacos.
Try taking a Spanish mother to this place and they'll not be easy to impress.
The food is served quickly, staff is friendly, and it has a pretty hip look to the place... the prices and a lack of a filler food (ie rice and beans) will leave you with an empty belly and feeling like you over paid.
For the regular hipster who wants to try mild Latin flavors with a Korean twist, this might be the place for you.
However you can not fool a Mexican that they should be paying $6-12 for a taco.
Just to note: I'm giving this place 2/5 stars not because the food is bad but because you can't convince my Mexican friends that they should be paying $6-$12 for a small taco.
