This is the only Denny's around here that I know of, and it is a decent restaurant. They need to renovate soon, though. The decor is 80s-ish and feels stale. And the staff are a mixed bag. Some are very nice. Others seem grouchy.
The pancakes remind me of those that I buy frozen at the supermarket. But the bacon and sausage were good. The prices here are really low, though. $4 for a breakfast at a sit-down place with wait service is pretty good to me! And you get so much food. I like it. It's a better value than the nearby Cracker Barrel or the Bob Evans. But then this is more of a low-end restaurant. The gist of it is this: It's one step above from McDonald's. Bring kids; they can share an entree with you if you aren't ravenously hungry. If you're just passing by Mount Laurel, this is a good place to stop. It's right next to the MacIntosh Inn and it is near the New Jersey Turnpike- Exit 4.
