Best place for Purikura in Tokyo

I'm going to Tokyo in February 2015 and want to know the best places for Purikura (the little photobooths that print out the photo strips for you straight away).
I'm taking my sister with me and think this will be a great, inexpensive souvenir. Plus, it's a lot of fun!
Thank you :)
