Anyone have any good recommendations on where to hold a one year birthday party?

We may have up to 50 people, but they'll mostly be adults (including a large contingent of Chinese inlaws) with only a few other babies.

Have heard people suggesting Gymboree, My Gym and Bishop Lei but wonder if they're really more suitable for 2-3 year olds.

Would be great to hear from anyone who's had a one year party at any of these venues (or anywhere else)?
