As if you really needed another good reason to kick back a cocktail or three, the Four Seasons Hotel San Francisco (757 Market Street) has started its annual Cocktails For A Cause summer program to benefit the Avon Walk for Breast Cancer -- yes, I know this year's Walk happened a few weeks ago. I'm a little slow on the uptake, but the good news is that the booze will be flowing all summer long anyway. Seasons Bar & Lounge Master Mixologist Sierra Zimei has whipped up a batch of specialty cocktails for the occasion, which will be served every Monday (that's tonight!) from 5:30 to 7:30 p.m. through the end of the summer. For more info. call 633-3000.
