Apparently this Dennys location doesn't understand the concept of service. A group of 6 of us came here for a breakfast before our flight out. We were seated at our table. After that no one came to our table to greet us, not even water was provided or a drink order taken. We waited twenty minutes till I went and spoke to a server who was hanging out in a group near the drinks, informed him of the situation, he asked what table we were at. Five minutes later, still nothing. We were completely ignored. So we left. On the way out informed the host that they had a table of 6 open now because they didn't serve us for 25 minutes. Absolutely the worst experience at any dine in location ever.
Vegas you will not be missed.
