Any leads for decent banquet halls in the Chicagoland area that can host a small reception (about 75 people) for under 3K?

Astoria Banquets has wedding packages that start at $19.95 a person for a luncheon.  Or, $39.95 for dinner.

Or, you might want to look into renting out a park district facility and hiring an outside catering company.  Chef Paul is an excellent catering company to work with.  They really work within your budget and the food is great!

Where in Chicagoland are you looking? 

Try Chevy Chase Country Clun in Wheeling. I am having my wedding there :)

Thanks ladies. I'm checking out two venues this afternoon. Wish me luck!!

@mwvr- How did the venues go???

If you are still looking, check out St. Andrews Golf Club :)

It went pretty well. Looked around the venues, spoke with the reps, and even had one tasting. FH and I are looking to book our date next week.

Thanks everyone for all of your suggestions.
