Today I polled my colleagues for caterer ideas for a holiday event at our house for my spouse's office. Here are the responses, in no order:
-Blue Heron Catering (510) 533-0781
-Barbara Llewellyn Info@BarbaraLlewellyn.com Telephone: 510.832.1967 Facsimile: 510.832.0419 (looks like she does teambuilding events built around one-day cooking classes too)
And for most creative (and thrifty) idea:
-Get food from Ann's Catering (of Rick and Ann's) and use Hostess Helpers (http://www.hostesshelpers.com) to can do the actual staffing.
