Here's one of the local and tourist top hits - Smitten Ice Cream. What's so special about this place, you ask? It gives you ice cream, as in, iced cream, the creamiest ice cream ever, and they make it right then and there at the front counter, in your presence at your witness (behind a fiber glass protective wall, of course).
At anytime on any given day you can expect a line here, because it's sunny California and the winter here is like a beautiful and warm spring day everywhere else. Urgh.
