If you want something really special, I suggest checking out Milat Winery. Bob & Mike are really cool and fun to visit. They have three cottages in the vineyard they rent out for about the same cost as a hotel and far cooler. They generally host a private reserve wine tasting in the evenings for the guests and a behind the scenes production facility tour and love hanging out with their guests. They have been there forever and know virtually everyone in the valley so a great source for recommendations on restaurants, balloon tours etc.. They generally offer case pricing discounts and their Port Chocolate Sauce is amazing.

The name of the restaurant used to be Taylors Automatic Refresher and a must do. Amazing food and not too expensive for the valley...
They were on Diners Drive Ins & Dives a few years ago and always have a line but definitely worth the wait.
They changed the name recently to Gott's roadside:
