The Diamond Perk

Stopped here from out of town. Amazing service and coffee. I got a specialty holiday flavor and my husband got French vanilla. We loved both.

On a scale of romances to textbooks, The Diamond Perk is a small-town romance novel.

The Diamond Perk offers indoor and outdoor seating, and they have a nice bathroom in the back. Paid parking is available directly in front of the shop or across the square (Sunday is free!).

My partner ordered iced lattes, and I indulged in a peanut butter cookie sandwich. I tried a new flavor, and I didn't like it too much. I just wish I'd chosen better. Otherwise, I loved everything about this shop.

The Diamond Perk is a great coffee shop right in the heart of St. Marys. The staff was friendly and willing to serve. I ordered an Americano, which was made to my liking. My wife enjoyed her hot chocolate as well. There is ample seating inside and parking out in front. If you live in the area or are driving through, stop by The Diamond Perk.

Stopped here while driving through the town. Cute little coffee shop. Lots a drinks and flavors to choose from. Super friendly and helpful staff. I recommend checking it out.

Really good, although it can get pricy if you want to add flavors and such. I loved the lavender vanilla latte with white chocolate sauce added on top.

Really creative coffee and tasted delicious. We got a chocolate strawberry matcha latte and loved it!

This was such a nice surprise to find this coffee spot while visiting St. Marys! I loved my Oatmilk latte and also got an iced coffee with the protein foam that was amazing! The staff was friendly & the service was great…I will be back on my next visit!

The atmosphere is so nice here and our barista (Kris) was fantastic. She was very helpful with helping me find a coffee I liked. Very pleased!

They had outstanding espresso, very nice atmosphere. Recomended

We meet here every week. Get my latte, maybe a muffin or breakfast sandwich. Wide selection of beverages, friendly staff, good company. My only complaint...need more table seating.

Always excellent coffee and treats 😋

A+ service at this quaint coffee shop run by a very friendly couple. The owner forgot my husband's flavoring and gave me a free coffee. The muffin I had was good too!

Great friendly helpful staff and the owner really make sure all the customers are satisfied awesome coffee recommend this place to anyone. Has a relaxing atmosphere.

Very nice friendly people. Coffee good. They actually bring it to your table which is a nice touch. I hope it stays open with the building selling !
