I've been impressed with the SF Chefs, San Francisco's Premier Food, Wine, and Spirits Week. This year's event is August 9-15 at a variety of San Francisco venues and mainly centered at Union Square. You must check out the Schedule featuring a variety of specialty events from cooking classes, sommelier luncheons, margarita and gin demos, Grand Tastings, and dessert events! The main registration page is here. Let me know what events and pairings you liked the best!
