You can check out their Lunch Menu @ King Estate Winery. Please note this was taken in late 2010. The menu items are subject to change.
That day, we had a BBQ tempeh served with a house salad and sweet potato chips. The sweet potato chips were light and crispy, and went well with the sweet and savoury BBQ tempeh. I would like to add some vegan-friendly buns or bread with them. We also had their light chardonnay, a wine county soda. It was a health and vegan-friendly lunch. Plus you have the view of their beautiful wineries. It is amazing that some wineries are able to accommodate vegan and vegetarian options.
