Celebrate Earth Day

Happy Earth Day! Though D.C. has become a whole lot more eco-friendly since the plastic bag tax took effect, there's more we can do. Many restaurants and other spots are holding special events today — here are some especially fun ones:

• Poste Moderne Brasserie will be roasting a 400-pound pig in the courtyard with $4 food and drink specials from 5:30 to 8:00. Proceeds will go to Washington Youth Garden and Beet Street Gardens.

• Jackson 20 kicks of its new “Late Night Blackout” Happy Hour, which starts at 11 p.m. The restaurant will turn off the lights and serve by candlelight throughout the spring and summer.

• The Phillips Collection hosts a special event in conjunction with the Georgia O’Keeffe: Abstraction exhibition. There will be a panel discussion with Maryland winemaker Robert Lyons, chef Nora Pouillon of Restaurant Nora, and Pennsylvania farmer Mark Toigo of Toigo Orchards about local food and the landscape. A tasting follows. The event, at 6:30 p.m., is $15 and free for members. Sign up on the Phillips web site.

• Tallula is holding a four-course sustainable dinner tonight at 7 p.m. for $85. Dishes include bison carpaccio, and wines are local Virginia wines with a smaller carbon footprint. Get more info and sign up here.
