Wine lists at many restaurants have recently evolved as a result of more consciousness about the needs of customers, you may be surprised at the lists of some restaurants and hotels when you visit. I suggest keeping an open mind and tasting different wines while here, as for the most part, US (read: California, Washinton, Oregon) wines are not widely available(except lower end, big production brands) You'll have an oportunity to sample wines from South American growing regions, Australia, many Europeans, Spain and South Africa while you are here, and many are delicious. Ask the manager or waiter if the wines are kept cool, a lot of places don't bother with ideal storage conditions and there are no cellars siting at 68-70 degrees around here. Ports, amontillados and so forth are available too!
I hope this helps,
