Service was good and there wasn't a wait when we went (around 4 PM). The place is small though, so I'd recommend grabbing it to eat in your car outside or to go. We had one signature cookie and one chocolate chip. Pretty tasty overall and the warming is obviously a must! Between the two, I enjoyed the classic chocolate chip more, but I'm sure the others are great.
If you're not a fan of certain ingredients (nuts, oatmeal), just make sure you ask before ordering!
