One of my readers mentioned that I should check out Stumptown Roasters. Through searching for it I came across Munchkin playland that opened up in Portland in the West Union Village Shopping complex. (Kind of far out!)

You can get your kids a pass and they can play for as long as they like. They also serve Stumptown roasters coffee and Beaverton Bakery pastries.
Your child has to be under 42″ to play here and prices start at $4.
These are all new things to me so let me know if you have been there and what you think of it!
