Would you buy a Dungeness crab from this man?

Well, you should, because Executive Chef James Chan of Bistro Boudin, 160 Jefferson St., 160 Jefferson St. near Pier 43 1/2 in San Francisco, has got a deal for you.

Through March, the restaurant will serve a once-a-week Crab Feast on Thursdays. You get one crab per person, linguine with slow-cooked tomato sauce, Caesar salad, and of course, Boudin’s sourdough bread.

Prices for the feast are $25 for one person; $49.50 for two; and $89.95 for four.

OK, the Niners might not have made it to the Super Bowl. ‘Nuf said.

But you can catch 49ers team members in another competition, the 7th annual Celebrity Crab Festival. They’ll be digging into bowls of Dungeness crab, noon to 3 p.m. Feb. 28 at San Francisco’s Union Square, to demonstrate the fine art of cracking the Bay Area’s premier crustacean. That will be followed by a timed crab cracking contest to see who can crack the most crab.

Watch all the fun, and purchase $5 tasting tickets to sample beer, wine, and crab dishes created by some of the city’s top restaurants, including Scala’s Bistro, and E & O Trading Co.

Additionally, for $20, you can get an autograph from a 49ers player. Proceeds will benefit the 49ers Foundation, which provides programs for disadvantaged youths.

In conjunction with this event, more delicious crab will be featured, Feb. 19 through March 1, at 54 San Francisco restaurants. “San Francisco Crab Week”is a promotion to showcase the city’s restaurants, and to draw attention to the region’s important Dungeness crab fishery.

Participating restaurants include Betelnut, Delfina, Incanto, and Poleng Lounge. For a complete list, click here. Diners who pay with a Visa credit card will receive a crab cookbook to take home.
