My wife and I went last night for the first time, and it was great! Just because something does not have reviews does not mean you should avoid it like the plague. The Createry has been up and running for about a year, and Molly is the owner. Which might explain why there aren't many reviews, and also, people tend to complain more than compliment.
Anyways, back to The Createry. Molly is the owner, and she did the session that we attended. She starts off with introducing herself and talks about the company/organization and then shows what the painting of the night is (which is on the Event Calendar). She also encourages you to go your own route, there are no limitations for creativity. You don't even have to do what is being demonstrated. When walking through the painting, she shows what needs to be done instead of just telling you so that both types of learners can understand. When it comes to colors, once again, she does not care what you do because it is your painting. She is willing to offer advice if you need it, or help mix colors if you can't quite get to it. She is very patient, but also fun to be around.
The concept of having this in a restaurant is a wonderful thing, but can also get quite pricey if you are buying drinks and food when you add in the cost for attending the event itself (our total cost ended up being over $100 when we added in the cost for the Groupon). But, do not let that discourage you.
The site is well laid out and the Event Calendar will show you the date, time, location, cost, and painting that will be there, and it is not hard to miss. Also, the FAQ lays out the rules and guidelines when it comes to not being able to make it to an event.
Overall, great thing that we went! Plan to be there for longer than 2 hours, because your creativity may take you a different route. Also, I highly recommend getting a Groupon, Living Social deal, etc. because I'm sure you don't want to justify why you can't enjoy the night. Definite recommendation.
