Little to no effort in making the food. I ordered a ultimate meat burrito and it was smallest burrito as well as messy. This is ridiculous it was the same size as one french toast sick.....do better

This is not a place to pay cash. I purchased a $3.99 breakfast burrito and gave them a 20. The guy would not give me change. The person who turned out to be the manager, said there is this thing called a tip, then walked off. If someone GIVES you something it is a tip. Taking what you think you are owed is called stealing not a tip. This place is breading entited theves.

Hadn’t been in a while and I hated it.
Music blaring into my open window while I’m trying to hear the lady talking on speakers from 1950s.
I’m frustrated.
