I take my 2 and 4 year old sons to Brat Pack to get their hair cut every few months. We always have a good experience there. They have tons of videos for the kids to watch while getting haircuts, plus bins of toys that fit on the chairs.
The stylists are very friendly and have been trained in how to cut kid's hair. The one time the stylist accidentally cut my son's bangs unevenly, they were more than happy to fix it.
There is a train table in the haircutting area for the kids to play with while waiting their turn. My boys love it. There is also a toy store in the same location.
