Ordered from the wrong location, Areli took down my order and made it for me didn’t charge me since I already paid or give me a hard time she was extremely helpful very polite & sweet
February 2026
I used the drive up stall. That was novel and fun for me. The server was pleasant and said she was learning to skate to make delivery more fun. The restaurant was clean and smelled like fresh food. The restrooms were clean. That is usually a good sign of good management and training. The tots were a little cool and hard but the produce on the burger was fresh and tasty.
November 2025
