Affordable baby shower venues?

Where do people typically host inexpensive baby showers? I've only been to a couple baby showers in my lifetime, and both were in restaurants, but the restaurants in my area have such limited capacity! Those with larger capacity are typically more expensive ($70-$75pp). I'm looking to spend no more than $65pp for food & drinks, as we're expecting a minimum of 50 guests and a maximum of 75 (it's a co-ed baby shower hence the high guest count), and I'm trying to stick to a budget of $7.5k total. Unfortunately our home, nor the homes of any of our family members would be suitable to hold that many guests either.

So for those that had a similar amount of guests and/or a similar budget, where did you hold your shower?
