moxicc It should be a great day here in Los Angeles next Monday. And since you're here during business hours - or what is considered standard business hours, the beaches shouldn't be too crowded.
My vote is hit up Santa Monica
SUN/FUN as you can lay out, walk the pier, eat at
great restaurants like
The Lobster,
Rebecca's for Margaritas or even check out celebs at
The Ivy at the Shore.
