Have you looked at Tuttle's Bowling Alley in Hopkins? They are at the interesection of Excelsior Blvd. and Shady Oak Rad. It's probably not as small as you'd like. I believe they have 24 lanes. However, they do host birthday parties and are very accommodating. We just hosted a family fun night there for our Minnetonka ECFE community and I think everyone had a very good time.
