I'm surprised there aren't more reviews for this place. My boyfriend and I did the "private 90 minute wheel class for two", and it was exactly as described on the website. Alex was our instructor, and he was a great teacher and made sure our pieces came out decent despite the fact that we were first-timers. For this reason, it's definitely worth it to do the private lesson. The class is long enough to make two pieces.
Also we had to postpone our originally scheduled class due to car trouble- I called literally 10 min before we were supposed to be there- and they were incredibly understanding and flexible on rescheduling. Much appreciated!
