SHAMROCK BALL

For a staid, grown-people St. Patrick's Day, cruise over to this casino event, sponsored by the California Irish-American Alliance. Why would a group committed to preserving Irish heritage in the Golden State produce a casino night with a partially hosted bar, gambling, and dancing for St. Patty's Day? Because the Californian Irish have a history of having a real good time, that's why.

Fri/16 7 p.m.-midnight, $85. Marines' Memorial Club and Hotel, 609 Sutter, SF. (415) 713-6341, www.shamrockball.com

FARLEY'S COFFEE BIRTHDAY BAGPIPES

The Guardian's staff respirates to the beat of our cups of joe from our neighbor up Potrero Hill, so we are pleased as punch to announce that our fave cafe is turning 23 — and as always, it's having a green-themed birthday party. To whit, live bagpipers will accompany your morning scone and paper. The pipers will play in the morning, other Irish tunes in the afternoon.

Sat/17 7:30 a.m.-9:30 p.m., free. Farley's, 1315 18th St., SF. (415) 648-1545, www.farleyscoffee.com

ST. PATRICK'S DAY PARADE AND FESTIVAL

Watch our city turn a shade greener as Irish dance troupes, marching bands, and hundred of floats make their way around West Coast's largest Patty's Day event. Celebrate Irish culture and history in an alcohol-free, yet still fun way — we're talking ponies, mechanical rides, and finger-lickin' Irish food.

Sat/ 17 Parade: 11:30 a.m., free. Starts at Market and Second Street; Festival: 11 a.m.-5 p.m., free.

Civic Center Plaza, SF. (415) 203-1027, www.sresproductions.com

FINANCIAL DISTRICT'S BLOCK PARTY AND LIVE MUSIC

HABITOT MUSEUM'S SHAMROCK DAY

Getting drunk seems to be the St. Patrick's Day highlight for many in San Francisco, but for kids the high point is usually pinching buddies for not wearing green and finding little emerald men in the clover field. At least at this event. Embrace your inner leprechaun and find gold at the end of the rainbow.

Sat/17 9:30 a.m.-12:30 p.m., $9 museum admission. Habitot Children's Museum, 2065 Kittredge, Berk. (510) 647-1111, www.habitot.org

IRISH BRUNCH, BLOCK PARTY, AND LIVE MUSIC

Bands like Blue on Green and the Whelan Academy of Irish Dance will accompany your boxty pancakes and Irish car bombs. Fifth round's the charm, right?

UNITED IRISH CULTURAL CENTER CORNED BEEF AND CABBAGE DINNER

For perhaps the most traditional celebration in San Francisco, head to this Outer Sunset hub of Irish culture. Load up on calories in the dining room with the center's ladies auxiliary-sponsored traditional Irish eats, then work them off to the live Irish bands that'll be keeping it lively.
