I hosted my kiddo's birthday party at Cha Cha Cha Milwaukie. We had lunch at the restaurant, then headed across the street to Wunderland for games and fun.
The manager and employees were super-attentive and kind in setting up the party and making sure there was enough seating and food for everyone. We had kids who were vegan and gluten-free, and the restaurant was able to accommodate with tacos, chips and guac.
I highly recommend this establishment - they are very family-friendly and the food was fresh and delicious.
