Wow, Charlotte is unfortunately not a good place for Red Robin. We thought it was an off day the last time we visited, however it's sad to say this place is awful. Last time we visited the food was cold, incredibly slow service, and it's only saving grace was the manager became our server because our waitress wasn't doing her job. Going in tonight we said why not another chance?? Well after sitting for ten minutes with no help, three servers walking by and not even an acknowledgement, the manager I think who looked at us get up and leave without trying to help, and other staff watch us walk by without even mistakingly saying thank you...we left. Dad because my family loves Red Robin. Need a new one or an entire new staff.
