I'm looking for a great 65th dinner for my parents. They haven't been to the City in a while. Very adventurous diners, not necessarily looking for froufrou environment, just something memorable. They've been to Aqua, Gary Danko. I was thinking of Boulevard, but see so many mixed postings...they already have plans for the Slanted Door, Incanto, and brunch at Foreign Cinema.
They know the City well, since I lived in San Francisco for a dozen years...
What do you recommend?
