Just went there. Food was fine, but bathrooms were locked. When my mother asked if she could use the restroom after we finished our orders, they said she needed to wait until they were done cleaning. After they were done, they ran away and wouldn't acknowledge us anymore. When we would make eye contact and start to get their attention, they would turn around and not acknowledge us. Totally rude and unprofessional.
