I came on cooler weekday after dinner, and there was still a crowd, but only about an 8 person line. We were served relatively quickly (other than the fact that the same person who was serving the ice cream was also the person filling the cones with marshmallow fluff - so she did about 20 of those before she continued serving patrons); definitely not optimized for service efficiency. The painful part is that a soft serve comes out at just under 7$.
There are 3 flavours, and you can get a combo of any of them, or just solid flavours. I had come to try the charcoal ice cream, so I went for black on black. One person took my order and one person serves the ice cream.
Overall, the ice cream just tasted like normal vanilla soft serve (is it bad to say that?), and the cone is a waffle cookie yumminess, the marshmallow fluff at the bottom of the cone was not my favourite, but makes sense from a practical standpoint.
NOTE: Charcoal ice cream (for some sciency reason I'm sure) makes your poop green! Not like a little off brown green, but like VERY GREEN! Just FYI fellow foodies!
