Two of us arrived at about 1 pm. The parking lot was full. Walked inside to nobody at the desk. There wasn't a sign staying "seat yourself", so we waited. There were two servers helping people, and they both made eye contact with us, yet nobody acknowledged us. We waited about 5 minutes, then left. Had someone just acknowledged us, that would have been fine, we would have waited.
On a side note, the metal stapler at the front desk is beige, and it is filthy. If they can't clean often-used items, I have to wonder about the cleanliness of the rest of the place
