Perk-Cup is definitely a convenient spot to drop by if you want something different or healthy without getting out of your car. However, I didn't have the best experience. I ordered my food in advance and arrived when they told me my food would be ready. When I first arrived at the drive up, I was food was still being prepared- that's fine; I didn't mind waiting a few minutes. I ended up waiting 10+ minutes at the window. Because or the issue, I was given a free cookie.
All of this to say, the food isn't bad but I wouldn't bet on your food being ready when you get there!
