help!

I need some suggestions! I do not know where to have my sons first birthday party! Our house is too small, and we have a huge annoying dog lol I don't want to plan for the backyard in case of rain or cold, (he's April 4th) and the club house by us is way too expensive to rent ($400). I don't want anything crazy, just somewhere simple that will hold about 50 ppl (we have huge families) 
Thanks!
