I'm literally holding myself back from going here everyday. It's THE BEST!
The owner is great; he was closing up shop when my friends and I popped our heads in and he still took our order without hesitation. The crazy ice cream concoction he made for us was done with great care and was sooo good.
This place is nut free, vegan/vegetarian friendly and takes credit cards (as well as cash). The patio looks like it can accommodate around 12-15 people.
I honestly can't rave about this place enough, you'll just have to come and try it out for yourself!
