Grabbed Sullivan’s one night for a quick dinner. We had a couple double cheeseburgers (those were good), a few hot dogs (nothing special), a chili and cheese dog (tasted good but the bun was too soggy, still good though), and some onion rings (would not get those again). Went back for some dessert and had a couple of shakes. Service was okay, not friendly and they closed early…said they were open until 8:30 but actually closed 15 minutes before that, we almost didn’t...

Great spot to grab a bite to eat and sit by the water while you enjoy with friends. The hot dogs and fries are nice to order and sit on the grass to eat and see the pretty view. The soft serve is to die for and great for the hot summer weather. Love coming here!

This was a fantastic food stand - don’t expect sit down restaurant service. The man that helped us was helpful, witty, kind, and knowledgeable. My husband got the recommended fish and chips which had a very healthy, and delectable, serving of fish. I had the scallops that were worth every penny, but as the man said - if you want the most expensive item, they’re great. Wish we lived closer to visit more often. We loved bringing our food to a picnic table and enjoying views...
