I was just at the portland? one a block off of the 205 exit on the east side. They had some 30ish games, most geared toward young kids and for good reason. There was also a play structure (tunnels) and a ball pit, in front of the stage area with a few rows of long tables for large parties. As for the pizza it was okay, a bit too greasy.
Now as for me, there were a few games I would have played, the rest I wouldn't likely touch. I don't know what the weight limit was for the play structure because I didn't go over there to read what it said, but most the time its not vary high but could probably support a 16y/o. Personally, I think bullwinkles in wilsonville would be a better place for the age group here, or at least something similar. There are better and bigger arcades, more physical activities to enjoy and more space without the 2-5 year olds to have to watch out for. Maybe there is a bigger chucky cheese then the one I was at, but I'd be more interested in some place bigger that's more age appropriate (not that bullwinkles ages 6-12, for most of it, is that much more appropriate for kids in their 20s
, but its stuff I would do). Bullwinkles is a bit out of the way for the portlanders, but its also closer for everyone down in corvallis/eugene.
