Have my two little brothers up (8 and 11) so decided to try this place. Several peanut butter sandwiches, including things like peanut butter with apple, peanut butter with banana, and even peanut butter with bacon. Also basics like toasted cheese and items like soups and salads. Smoothies and big cookies, too.
The interior walls are essentially chalkboards for the first half or third of their height and each table has chalk and an eraser. My brothers and I got several games of tic tac toe in before our food came (and I went undefeated). I didn't order anything because food for nostalgia's sake isn't my thing and I was never much of a peanut butter sandwich eater (though peanut butter and pickle was a delight my dad taught me). One brother got the toasted cheese and one got the peanut butter and bacon (big louie). Each were about $5 and came with chips and carrot sticks. They were full-sized sandwiches. The toasted cheese used Tillamook and had a little too much cheese if that's possible. I had a couple quibbles with the peanut butter and bacon sandwich: a) the peanut butter is the natural kind and so not very kid-friendly (my brother later said -- luckily saving it until we left -- that it tasted like "crap"), b) the bacon was the thick-sliced variety and cooked until crispy leaving some of the parts a little tough for him to bite through. The cookie, btw, was totally mediocre, sandy and a little chemically.
It's a decently fun place with cheap enough prices and a suitably interesting menu if you like peanut butter sandwiches. The toys and stuff definitely lean towards the preschooler, but the chalkboard provides enough entertainment for most kids.
btw, the address is 1325 NE Fremont, on the north side of the street next to several other little places. The signage isn't good, but it's there.
