My husband and I will be arriving in San Francisco late on a Wednesday night and heading on on Friday afternoon to spend the weekend in Napa. That means we have one night for dinner - Thursday. We are staying at the Clift Hotel in Union Square. We are looking somewhere with a younger crowd, good atmosphere, trendy, some good drinks and preferably small plates (though that isn't a necessity, just a preference). From doing my research online and specifically on this board, it looks like the Mission area is the place we need to be. Is Medjool a good choice? Any other recommendations? I understand we can only book the main restaurant with a reservation - not the rooftop. Should we opt for no reservations and wait for a table on the rooftop - is that the better atmosphere?
