You probably have a few favorite hang outs in San Francisco. You've gone to them for as long as you can remember, and the drinks and food aren't outstanding but aren't bad, and maybe the service isn't that great, either. They won't win any major awards because of their menus, architecture or history, but they're reliable and full of character. San Francisco Architectural Heritage is trumpeting such places--like Sam Wo, the Tonga Room, Cafe du Nord, and the Top of the Mark--as cultural legends that deserve recognition. Read about these "legacy" bars and restaurants, and on Saturday, join a free community conference about preserving the city's cultural identity.

On Sunday, of course, it's time to recognize dads. If you're looking for some ideas, check our Father's Day guide.

San Francisco is bubbling with the excitement and energy of a 9-year-old, and has activities to match. Dodgeball, skating to disco tunes, circus performers, a shrimp-&-grits cook-off and free admission to the Museum of Craft & Design are happening at Sunday Streets in the Dogpatch-Bayview neighborhoods. This is also the weekend of the annual Live Oak Park Fair and SF Free Folk Festival. And pig races and carnival rides, documentary films and dance from around the world are ongoing; our June calendar has the vitals.

The countdown has begun to 5:45 pm Sunday, the time when the Museum of Modern Art will close and won't open again until 2016. MOMA's farewell party (through June 2, 2013) includes gallery talks, access to all of the exhibits, a series of how-to, tell-all demos hosted by The Kitchen Sisters, and a final parade on Sunday, all free. For insomniacs, a variety show (with live entertainment) and the enthralling video "The Clock" run 24 hours from Saturday through Sunday evening. Our MOMA timeline spells out cool and impressive stuff you should know about the museum.

And if you prefer to ditch art and the inevitable crowds, our May calendar lists other options.

On Tuesday, May 28, many of us will be dragging ourselves into the office, quite possibly party-weary and burger-and-beer-bloated from the long Memorial Day weekend. An antidote? Maybe on a shelf at Walgreens, or at the W San Francisco that evening.

There, a dinner of wholesome fare includes onigiri with kale, ahi tuna with ponzu and avocado, wasabi summer squash, American Kobe beef tataki, soba noodles and glazed salmon with pickled cucumbers. Even dessert is relatively healthy: Brown rice pudding, and green tea cheesecake garnished with blueberry mochi. The one-night-only meal is a collaboration between the W and Onigilly, which began as a food cart and added a Financial District cafe in 2012.

In the world of San Francisco food carts and trucks, Onigilly has one of the most health-conscious menus, since it's focused on onigiri, traditional Japanese rice balls. Onigilly's onigiri are seaweed-wrapped bundles of organic brown rice with light seasoning and fillings.

Tuesday's dinner is one in the Local Motion series of meals created jointly by the W and local food trucks. Part of the evening's proceeds will be donated to La Cocina, a food-business incubator that supports low-income entrepreneurs, mainly women and immigrants. Onigilly owner Koji Kanematsu, who came to the US in 2006, was La Cocina's first male graduate.
