Have a drink for a good cause Sunday at the Red Derby. (Evy Mages/FOR THE WASHINGTON POST)

The Red Derby is hosting a fundraiser called DASH Day. All summer, the Red Derby has been collecting school supplies for the District Alliance for Safe Housing, a nonprofit group that supports women and children who have been victims of domestic violence. The goal, Red Derby co-owner Sasha Carter explained in an e-mail, is to provide 63 kids with “paper, binders, notebooks, pens … everything with which a student needs to start off the school year.”

Order any New Belgium beer (Fat Tire, Ranger or Shift) or cans of Natty Boh or PBR and all proceeds will be donated to the back-to-school drive. A selection of mixed drinks will also be pegged for charity, so ask at the bar. Stop in from 11 a.m. to last call to contribute to the cause.

Further south, congratulations are in order for the Wonderland Ballroom, which is celebrating eight years at the corner of 11th and Kenyon streets NW. Wonderland was a real trailblazer in the recent evolution of Columbia Heights — the first hip bar in the neighborhood. (In the interest of history, Wonderland replaced Nob Hill, which had been the city’s oldest — and only black-owned — gay bar.)

Wonderland is marking its anniversary with an all-night happy hour, which means $2 off draft beers and $1 off mixed drinks. Grab a Chocolate City beer (Wonderland bartender Jason Irizarry founded the brewery) and enjoy it at a table in the comfortable beer garden.
