Had a craving for some frozen custard. I got the mini turtle sundae. Excellent customer service, and the frozen custard was delicious as always.

First timer - tried the small turtle sundae—- but as spectacular. Very smooth creamy custard. I’ll be back, I noticed they have a ‘tin-roof’ sundae, I’ve been craving one since my first and last taste nearly 10 years ago (Leon’s Custard)

We just made our trek from St Charles area. Best custard ever, check out the pistachio! We have been loving Greg's 12 years! Tall Dark Italian totally recommended! But check the calendar!

Its a nice ice cream. Lots of flavors to choose from but I have had better custards. Loved their choices of flavors though. Bit pricey for the quantity.

6th best frozen custard in the US, and did not disappoint! Classic flavors and really great topping combos, overall would definitely visit again! Perfect Summer night sweet treat 🙂

Tried the butterscotch flavor and it was pretty good! They didn’t have it available for cones or cups, so I picked up a pint instead. The custard is creamy and has nice flavor, but not quite top-notch for me. Still, it’s a solid spot with good quality treats and worth checking out if you’re nearby.

A treasure of the northern suburbs. Greg’s Frozen Custard has some of the best quality desserts in a fun atmosphere. They have your standard chocolate and vanilla flavors as well as daily specials. There’s a large selection of sundaes and toppings that there’s definitely something for everyone.

Greg’s does not have indoor dining, there’s a walk up window and plenty of covered picnic tables and a few benches alongside the building. The entire place has a 1950s retro aesthetic and they’re often playing music from that era as well. The entire package is comforting and something to look forward to.

My go to sundae is the dusty road, which is vanilla custard with hot fudge topped with malt powder and a cherry. You can’t go wrong with the Elvis or the Fluffernutter as well. They have a selections of shakes and malts that always hit the spot as well like the dreamsicle or lucky charms shake. You can get treats like a banana split which is massive and with fresh toppings.

You can typically get a calendar of their monthly flavors on social media so you can plan out any special flavors. It’s worth checking out so you don’t miss anything that piques your interest.
