Great spot for smooth and rich ice cream in the Lancaster area! I've been a number of times when in the vicinity for a church retreat, and it's one of our traditional stops for break time! They have some interesting flavors and add in a few here and there, which adds some good variety.
They're also very cognizant of gluten sensitivity - when my wife has mentioned it, they go get untouched ice cream from the back!
Overall a nice experience, and that's probably why they get pretty crowded.
