The Buckeye, one of Marin's best restaurants, is a block away. Walking paths a few hundred feet from the condo will take you to Sausalito (about 2 miles south) One half mile along the way is Davy Jone's Deli— a GREAT sandwich deli (inside the bait shop). Another quarter mile is Fred's Breakfast, which is a local favorite and highly recommended. As you get further towards Sausalito, more restaraunts abound. The ferry to SF is in downton.
Walking in the other direction towards Mill Valley, one path takes you to The Junction (about 1/2 mile away) which has great pizza, salads and beer. Weekends they have music (seasonal?) Almost exactly across the street is Good Earth which is like a Whole Foods, and has excellent prepared food, salads, etc to go. Close by, you can connect with the Tennessee Valley trail network
The Manzanita Park 'N Ride (across the street from the Buckeye restaurant) is a major stop for the Mairn Airporter which takes you directly to SFO. Golden Gate Transit also stops there with service to SF and the rest of Marin.
