I split a chicken Alfredo and a grilled cheese sandwich. Both were wonderful. I'd definitely eat here again next time I'm in town.

I am not sure why this place isn't crammed busy ALL THE TIME! My wife and I and our two kids had an awesome meal here 6-11-25. The employees, and what I assume was the manager, could not have been nicer. I mean seriously they should probably give lectures to OTHER restaurants on customer service and just all around being nice people! I HIGHLY RECOMMEND GRANDPA MAC! Are we frequent Rehoboth at least one to two times a year We will definitely start making this a mandatory stop!

Food was bland. Upon entering the restaurant, the cashier was cleaning/emptying out the trash. All while tending the register and handling the food, not once washed her hands nor had gloves on.

Best mac and cheese I ever had! Fresh ingredients. More options other than mac and cheese. Kid friendly . Casual, no waiters. Free parking. Free play old school video machine in store. No sales tax in Delaware! Friendly staff. I will be back! 🤩

Food was great and staff was amazing. Got take out and waited and the staff was great with the kids coloring pages and helping with a spull our 4yo made. As a parent, it's rare to find! Will definitely be back.
