"A unique coffee shop that enjoys a twist on its name, a parody of the more famous GM Proving Grounds test track. Don't be fooled, just like it's counterpart, this coffee house and ice cream shop puts out some awesome stuff! Coffee, mocha, cappuccino and of course ice cream, are all available at this awesome coffee house! Take in the nostalgic feeling decor as you enjoy a hot coffee, especially as the weather cools off here in southeast Michigan! Come enjoy a nice coffee or ice cream during your next visit!"

"If I could give 6 stars I would! My husband and I have been in town all week and visited every night. Where do I begin? House-made syrups, fresh roasted fair trade beans, Guernsey ice cream, beautiful indie/rustic decor & lighting, and “Marvel” tip jar competitions?! Sweet/Friendly staff. Everything was equally delicious & delightful."

"Ah, Proving Grounds… what a gem! This place has become synonymous with warm memories for me, my coworkers, and my family. My daughter lovingly calls it “the one with the ice cream cones,” which just melts my heart. The staff are always pleasant and helpful, the food is consistently delicious, and the atmosphere is cozy and welcoming. It’s a spot I find myself recommending often, both in my personal life and my work life,because it never disappoints. Proving Grounds truly has a special place in our routine, and I’m grateful for the experiences we’ve had here."

"Cool place to pop in for coffee or ice cream, take a meeting or "work from home". Plenty of seating. Chill environment. Music volume is perfect. Staff is friendly and helpful. They serve hot coffee, hot cocoa, cold brew, pour overs and much more! They even roast their own coffee beans!! What?! During my brief visit today, the place was frequented by dad's and kids, business professionals, church members and teens - hanging out. What a fun space!"

"Really like the coffee. The employees were a bit rude mainly the one taking our order. Service was quick though. I had the oatmilk latte with vanilla and lavender and an avocado toast. They were busy which I completely understand but I don’t think that excuses the shortness and rudeness while my order is getting taken."
