I will be traveling with my wife and two other couples to Napa/Sonoma in October to celebrate my 50th birthday. My birthday falls on Wed. the 19th, and I want to plan a fun night out with great food/wine/cocktails. I don't need the most expensive eatery in the valleys, but cost is generally not an issue. I was thinking a guy spa day pampering myself, followed by cocktails, wine, food and general 50th birthday party debauchery in a festive atmosphere. Any suggestions?
