- MPMonica PachecoDec 16, 20251.0This place is trash please people stay away from this place my sister and I ordered food from there as separate times but the same day and she had a hair in her food and my daughter had a hair in her food so disgusting. The staff is rude as hell nothing but young kids that don't give a shit about people and their food all they do is mess around and talk about partying with each other. They need to bring in people that does their job right that value people and the food this can make people very sick!!!!!!
