Definitely consider Stella Mares - at the Bird Refuge right across from the estuary by the zoo. Lovely spot, very good menu and sound wine list. A local favorite in an old historic French Empire style mansion with an elegant greenhouse dining annex Modestly priced for Santa Barbara - look up their website and see if this is what you are looking for. http://www.stellamares.com/
Here is their wine list: http://www.stellamares.com/assets/pdf...
Cafe del Sol is also in the same area at the Bird Refuge, Mexican, stiff drinks and more modest.
Both places are a direct approx 15 minutes walk along scenic the bike path walkway along the edge of the bird refuge from the zoo.
