It's really up to the restaurant in DC, no matter what they tell you. Bistro Francais and La Chaumiere are $15 which is my limit for corkage. The Caucus Room is the most wine friendly place I've been to. They've waived corkage whenever I've gone and their stemware is excellent. Best advice, call ahead and ask. Be a good corker and offer wine to the staff, tip well, and maybe order a bottle off the list as well AND don't bring anything cheap (why bother?). Jay
