Good places for birthday parties?

We'll be celebrating our dd's 3rd birthday soon.  We have had her first two parties at my parents' house.  We'd love to have it at ours but our house is smaller.  It would be really hard to have the party inside if it happened to rain. 

Do you know of any places around that would be fun for a party?  We're pretty flexible on the area -- Royal Oak, Madison Heights, Troy,  Roseville, St. Clair Shores, or anywhere a little north or south of any of those towns would be fine.

 Thanks!
