Bay Cities Italian Deli & Bakery in Santa Monica makes THE best sandwich in town - the Godmother. Bay Cities has an incredible gourmet market too. I really recommend ordering online to avoid the lines.
I like to ride my bike along the boardwalk from Back on the Beach in Santa Monica, where I have my early morning coffee, to Abbot Kinney in Venice, then back for breakfast at Back on the Beach, feet in the sand. I don't do it as often as I'd like to, but when I do, I LOVE it!
I love going to the theater in town - Mark Taper, Dorothy Chandler, Pantages, Kirk Douglas - then out for a drink and dinner! If it's a movie kind of night, the theaters in Westwood are my go-to: big screens, and plus, they're never jammed. Also, the Laemmle theater in Santa Monica is great too.
