Recommendations for small wedding reception

My fiance and I are going all out and spending the extra $10 to get married at the cultural center (instead of just at city hall). I'm somewhat of an anti-bride (my wedding dress is knee-length and kelly green), so the thought of a traditional wedding reception turns my stomach. We've decided to go out to brunch/lunch after the 10 minute ceremony with our immediate family (about 16 people with a few kids thrown in for good measure). I'm looking for suggestions as to a good spot to celebrate on a Saturday during brunch/lunch hours. I don't want formal or haute cuisine (his parents are from Iowa, anything that comes across their plate that they haven't seen before is automatically "interesting", not in a good way). Food quality is definitely a priority over atmosphere. A private dining area and liquor would be fantastic as I don't know quite how well this group well meld together I have a budget of about $1000 (minus $45 for the license and ceremony fee). I've already threatened Stuckey's (mom was not amused at the prospect of pecan logs for everyone). Any ideas???

Thank you!!!!

Do you want it to be downtown or are you willing to travel?

Willing to travel for good food!
