I went here for the birthday deal (free grand slam) in the morning. I was seated promptly and the waitress came within 5 minutes to ask if I need a drink. I had some water and then informed her that I was just here for the birthday deal. She asked for some government id to verify and apologized for the inconvenience and said it was protocol. She was really nice and helpful throughout, unfortunately I didn't get her name.
Anyways, normally you get the traditional grand slam but I explained that I couldn't have meat so she offered to ask and see if she could replace the bacon and sausage with something else. Luckily she was able to and I got to replace it with hash browns and an english muffin plus the regular pancakes and eggs.
It tasted great and was super filling! The service was fast and the food was perfectly cooked!
They gave big portions and I couldn't have been more satisfied.
Just have some money extra for a good tip because the waiters/waitresses deserve it.
It was a great start to my birthday so thank you Denny's!
