Their tortillas are disgusting. That's probably the real reason why.
Secondly, nobody there seems to know how to fill them or wrap them properly, so first they are spilling out everywhere as it is too loose and then you get a lot of bites with just one ingredient at a time.
They suck now anyway, just go to a real Mexican place or at least Rubios if you're going to overpay for a burrito, although if you're doing the latter you'll be still better off going to a Greek place.
