Much to the delight of families everywhere, the The National Museum’s “Lego Architecture: Towering Ambition” has been extended through Sept. 3, 2012. (Courtesy of Adam Reed Tucker/NATIONAL BUILDING MUSEUM)

The arts

A National Cherry Blossom Festival that blooms bigger and a touchy-feely exhibition at the Hirshhorn top our list.

Bars and clubs

Coming soon: rooftop taquerias, more local beers, icons expanding to suburban Virginia and the rebirth of a historic Petworth night spot.

Kids and families

From “Alexander and the Terrible, Horrible, No Good, Very Bad Day” to towering Lego exhibits, make this the year you expose your children to the arts.

Restaurants

Look for more ramen, more Mexican, more sandwiches from the Taylor franchise and the arrival of Philadelphia restaurateur Stephen Starr.
