The outdoor ice skating rink at Rockville Town Square has closed for the season, but pizza and candy will keep the kids busy in downtown Rockville this spring. Mellow Mushroom, the pizzeria taking over the former Oro Pomodoro space on Maryland Avenue, has set its grand opening for May 2nd. (Click here for more on the Rockville Mellow Mushroom, which will cater to families and large groups.) Also new at the Town Square is the candy store It’Sugar, which opened on Gibbs Street last weekend with nostalgic sweets and giant boxes of Nerds, Kit Kats and Sour Patch Kids. This is the seventh D.C.-area location for the fast-growing candy chain, which also specializes in bachelor party fare (candy undergarments, anyone?) and will be open late most evenings.
