What People's Say About Place

This is simply the best custard. I've been coming here since the 1960's. It's always been a hot spot for teenagers in the summer, cruising the main drag and being seen. The Gille burger is a beef loose meat sandwhich, with its own very distinctive sauce and the hot beef sandwich is dependable good, they both are.

I love historic places. Not to mention this drive in has the best food! The cheese curds were the best I've ever had! Not those gross frozen ones. My blueberry malt was amazing. The server we had was super friendly. Going back real soon.

Giving the old girl a 5 for nostalgia alone. 2 hot 4 the drive up. So we ate out back in the shade. Great place, a must go when your in fondy in the summer

First time going! We dont live in the area at all and passed a few times visiting in town. So we decided to stop in this time! Super great pricing! Excellent service! And really good food! Definitely will be back!

Very good service and great desserts. Feels like your back in 50s at a drive in. Really classic experience and quality food and desserts. A must try if you are in Fond da lac!

A friend recommended Gillies to us, we had never been there. We absolutely LOVE the old-time drive up diner feel. The staff is so nice and the food is absolutely delicious! And let's not forget to talk about the prices. While everything else has seemed to sky rocket and become unaffordable, we are still able to afford Gillies generous prices and have a nice family outting and meal without breaking the bank. Gillies also has the most amazing ice cream! I will not willing eat ice cream anywhere else besides Gillies. If you have not tried it, we highly HIGHLY recommend that you do! This has become my family's favorite place.

literally the best drive in. Everything about this is perfect. Cheese curds are so yummy. The burgers are good and the sundaes are even better.

Gillie Cookie (Ice Cream Sandwich) (10/10) Peanut Butter Malt (10/10) Mac'n Cheese (10/10) The Mac'n Cheese was a sleeper. I'm pretty sure no one realizes how good it is.
