We were so impressed at the descripton and the photos that we went with the CHEF and others in September, with the only change being a "Motown" band and perfect weather.
The deal is a modest fee (about 20 bucks each) which allows admission, unlimited wine tasting, buffet, and entertainment. Guests seem to amplify that by bringing chairs, tables, appetizers, etc. No coolers or alcoholic beverages are allowed but, hey, I didn't see anything.
It was a great time, nice venue, there was a dance floor filled with partiers. The food was good, a heck of a time, if I can brag just a little. I'd go back anytime. Turn the audio on and press Play to enjoy.
