If you make it north of the Gate above, and you'd like to check out a small seaside town AND a sweet bike shop, definitely stop in Sausalito and Above Category. You can easily make a day (or more) out of this town... touristing, shopping, etc. I don't think you'll be bored.
I really only stopped here for the bike shop, and it did not disappoint. It's really well done. Merchandise, selection, staff, etc. If you like bikes, this is a place to visit.
I was impressed and humbled by the amount of Dario Pegoretti bikes on display (RIP). Gorgeous stuff.
