I ordered the Fruity Pebble frapp and it’s so good! Since there was no caffeine I was able to order a few of the same drink for my kids and husband who are sensitive to caffeine. They also loved it. I’m happy to see businesses like this bringing the mall back to life. The drinks and service were 10/10.

Grabbed the iced white mocha with raspberry cold foam this morning- absolutely amazing! 10/10 will definitely be back soon!

This is my Saturday Regular stop for their Lotus Energy Drink, they are all great, I have had them all. I make it a point to bring my Cat, Luna, in her a Backpack and we go on our Saturday Adventure. If you go, maybe you'll see me there.

Super tasty drinks and friendly staff! I got the Orange dreamsicle today and it was delicious.

The frappe: After watching the baristas struggle and get yelled at by the boss for 10 minutes trying to get the doors open, I patiently waited . Their coffee set up looked to be a single dose espresso machine and it took a bit. They should look into commercial machines . The frappe tasted like milk and torani syrup. The straws weren't thick enough to drink the frappe. I dont think I will be coming back to this shanty again. Especially when they also have the highest prices in town and the most inconvenient location .
