My experience was horrible, I’m never coming back! The food was good and the waitress was nice but while we were eating a mouse ran past our table and one of my friends accidentally stepped on it. The mouse was convulsing while we were eating and the owner still made us pay full price. She wouldn’t even look at us!! Smh
