I am looking for a nice restaurant to take my parents to after we spend Saturday morning at the Japanese gardens in golden gate park. Does anyone have suggestions to nice sit down places within walking distance of the east end of the park (Stanyan)? It would be especially nice to be able to eat outside. I know there is a new place called Bia's on upper haight that has garden seating out back. Is Bia's a good brunch/lunch place?
