This place is closed. There is a fence up around the building and there is nothing left inside. Doesn’t look like a remodel.

Im not sure the staff name that helped us out either Evelyn or Yvette. She was super sweet. Very very kind. Id go back because of her. Food was good too. Smash burgers are juicy with tots. Got a strawberry shake as well 😋 so good. Fast service and not crowded. I ordered outside as a walk up but it was cold so I went to my car. They brought my food right out. Very nice!
