I’m never the type to write reviews but I am disgusted. I had ordered an ice coffee from here and there was a dead cockroach in it. ???? There’s no point in calling them to get an apology or get compensated for a “free meal” because why would I ever want to eat from there after finding that dead roach. Also I would much rather leave the comment here that way people know how clearly unhygienic this place is.
Always contains great meals, fast and ready. Employees are always nice to customers!
Rude service most of the time, specially from the women in the drive thru. I ordered two plain tacos for my daughter the other day, and what I got was a tiny portion of nasty looking burnt meat smothered on half of a greasy taco shell.
