The standard industry phrase, as I understand it, and according to references I have been eble to find, is "catering minimum."

"There is a $5000 catering minimum for an evening wedding and $1500.00 catering minimum for a daytime wedding. Click here for a sample evening catering ...' "
www.thecliffhouse.com/cliffhouse/html/Weddings.html

"Catering minimum: $4000 (food and beverage only*) ... *In addition to catering minimum: 20% service charge, 8% sales tax, and a $150 set up fee) ..."
www.indyzoo.com/content.aspx?CID=714

"You must meet the catering minimum, which means you'll be spending AT LEAST $80 plus service fee & tax on food & drink for each person who attends your ..."
www.mouseweddings.com/disneylandwedding.html

"Regional American cuisine; catering minimum $1000. Diverse catering plans available- they'll cater picnics, weddings, luncheons. ..."

I've booked a lot of private/banquet rooms in restaurants at part of a previous job, and the entire last line would be best translated as:

Minimum food and beverage charge of USD 4,000
