I went my first time right on the day it opened so the line up was very short and I didn't have to wait long. The experience was great and the ice cream was even better! The location was small, but very cute. I was excited to go back.
I returned with my friends a couple weeks later and stood in line for close to 45 minutes. Once I got inside the store the person at the cash register was very short and laughed at us for asking for substitutions. Warning - this place does not tolerate substitutions. I ordered an ice cream and was extremely disappointed. It started melting within seconds and the taste was not creamy and hid behind all the toppings.
Verdict: Go to Baskin Robbins instead.
