SUSHI STYLE: Go, people, go while you still can, 'cause Go Mama Go is slated to close sometime within the next couple of months -- a clerk told us recently they're thinking the end of March. In the meantime, the place is still packed with goodies. Stock up on cherry-blossom sushi sets now, since the store will likely be closed before the actual cherry blossoms start blooming. These come in blue, yellow, sage green and salmon, with plates ($12) and bowls ($6) reasonably priced. GET IT: Go Mama Go,1809 14th St. N.W.
