I visited the shop for their ice cream sandwich in the summer when the line was out the door and it was definitely worth it. They make their own ice cream and cookies
I recommend getting the sandwiches cut in half as it's easier to eat 2 halves.
On a more recent visit I had their chocolate cake which was perfectly moist, and a good ratio of cake to icing.
Just a heads up: the place doesn't really have any seating in the winter.
