I'm sure this topic has arisen before, but I figured I'd ask anyway: Â I'll be spending a 4 day weekend in San Francisco next week, and I'm looking for recommendations as to the very best places to maximize the limited shopping time I'll have. Â I'm fairly familiar with the big stores (Nordstrom, etc.) in the Union Square/Market St. area, and wondered if there are any tucked away/only-the-locals-know kind of places to check out. Â I'm interested in anything from high-end tailoring to street/athletic wear. Second, and nearly as important, is this: Â I'm long overdue for a haircut, and my local regular girl isn't around. Â I'd appreciate recommendations for the very best haircut in the City by the Bay. Â Old-school barber shops for $15 or upscale salons for several times that are both up for consideration -- where would you go if you had one haircut to get in S.F.? Â Thanks much, gents.
