Everybody likes a little trouble now and then . . . some of us more than others.  I began Sunday on the west side of San Francisco in Ocean Beach with a double espresso at Trouble Coffee.  Trouble Coffee's a refreshing antidote to Starbucks . . . a bare bones operation . . . no add-on sales . . . just strong coffee drinks, coconuts and toast.  Why coconuts and toast?  I have no clue.  But that's the deal at Trouble Coffee.  Stop by and ask Giulietta.  She comes across as a straight shooter—I bet she'll give you an answer.  Oh yeah, there are dilli beans too—spicy delicious pickled green beans—my hostess with the mostess bought a jar and they ended up in bloody marys by early afternoon.  I love the shop's sign . . . the waves across the "f"s reflect its beachside location . . . and the drill on the sign is certainly appropriate given that the place feels more like a workshop of some sort than a coffee shop . . . tools hanging from peg-boarded walls and falling out of tool boxes.  Stop by and check it out . . . but you might want to think twice before ordering a double-mocha-half-fat-skinny-tall-corn-syrup-jive-ola-coffee-beverage . . . it really doesn't feel like that kind of place.
