Weekend must-tries: Mardi Gras special; new on South St.; great sushi in the burbs

Who's your crawdaddy?

He would be Mark DeNinno, chef-owner of Chris' Jazz Cafe in Center City, who ships in tons of fresh-crayfish (or crawdad) from February through late May. Goes well with the Mardi Gras theme. The sweet-meat, fresh-water crustaceans are put to multi use: mac and cheese, crawdaddy cheesesteak (ribeye), pot pie, fried in an empanada as a "craw-zone," and sold in a bucket with an ear of corn and boiled potatoes.

While we're at it, DeNinno adamantly denies a rumor that Chris' is changing its name; he acknowledges that the landmark will broaden its scope of entertainment to include other kinds of music and comedy.

Chris' Jazz Cafe, 1421 Sansom St., 215-568-3131.

Sushi in the burbs.  Sushi is so much about presentation. Beyond the artistic plating, you need ambience. Well, you get beautiful rolls, elegant atmosphere and great taste at Umami Umami, which opened nearly two years ago in the century-old Dresher Inn.  (It's unrelated to Umai Umai downtown, by the way.) Though Umami Umami's upper-level dining room might be a bit over-chandeliered, seek out the sushi bar, tucked off the main entrance. Share a tower ($17), which layers wild rice, crab mix, avocado and either spicy tuna or spicy salmon. Then order your own Crunch N Munch ($12, seen here), which stars spicy tuna on top of tempura flakes, cucumber and crab.
