Pretty good place overall! I LOVE all the Mac and cheese options and variations. I love the vegetarian and vegan options too. The fried Mac and cheese bites were good as well as the Mac grilled cheese. The vegan Mac and cheese was okay and rather weird. The spices in it were strong and I just wasn't really interested in it. Otherwise pretty good. Place was very clean and staff were friendly. Both bathrooms are also unisex, which I love!

We ordered take out and were delighted by the customer service. They forgot to pack a portion of our order so we had to go back so that sucked but the food was great! The flavor combinations are awesome!!! I wish I had added more sauce, but I can’t wait to order again regardless

I visited over the summer, and Grandpa Mac is fantastic. I have Celiac, so this was a perfect place to go. The staff was so friendly, and both times I went the guy who was working at the counter (different people each time) explained that they kept the gluten free pasta separate, everything was prepped separately, and reassured me that they could serve Celiac customers. The artwork featured in Grandpa Mac is really cool, and it just has a great vibe. I wish I lived closer because I want to go back all the time!

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!

Terrific fast casual find that offers endless varieties of made-to-order mac and cheese. The staff was extremely friendly and was more than helpful in guiding me to piece together a custom pasta creation. The ingredients were fresh and the pasta was perfectly cooked. Artwork line the walls throughout the colorfully decorated restaurant. Overall, a fun and delicious experience for my family and I.

Enjoyed going to Grandpa Mac’s. The service and food were great. Will definitely go again when we are in Rehoboth for our yearly beach trip.

Nothing wrong with service, just not a waitress/ waiter kind of place. Workers were pleasant. Fried macaroni was excellent with a side of sauce. My daughter and I split a meatball panini and a chicken pesto one. Both were good but we decided we liked the meatball one better. Came with chips but we had to ask for those as well as a straw due to the dumb Delaware straw law.

We ordered the Mother Clucking Bacon Ranch and it was delicious. You order at the counter and someone brings the food to you. The service was quick and friendly. The restaurant has a fun family family-friendly flair. We love the free Ms Pac-Man machine.
