Can’t make it to the excellent Mad Fox Brewing Company during the week? Don’t worry — all the regular house-brewed beers are $2 on Saturday and Sunday afternoons. (Evy Mages for The Washington Post)

Number Nine
The sweet-looking P Street gay lounge — formerly known as Halo and Mova — offers two-for-one drinks from 5 to 9 p.m. every day of the week.

El Centro D.F.
The two rustic-styled bars on El Centro’s wide-open rooftop serve up $4 drinks from 5 to 7 p.m. every day, including margaritas (frozen or on the rocks), Mexican beers and house red and white wines.

(See five more ideas after the jump.)

Ceiba’s Latin-American specialty drinks (caipirinhas, margaritas, Cuba Libres) are $5 every afternoon, and Dark and Stormy cocktails are $5 all weekend long.

Looking for a pre-concert happy hour? Head to DC9’s roof deck for $2.50 bottles of Bud and Bud Light, $3 rail drinks and a $3 selected beer of the week until 8 p.m.

Lyon Hall
The food is almost as much of a draw as the drinks at Arlington’s Lyon Hall. Between 4 and 7 p.m. every day, a selection of drafts are $3.50 and glasses of French and Austrian wine go for $5. Pair those with $5 gourmet frankfurters or a $10 pot of mussels.

Smith Commons
Not only does Smith Commons extend its popular Smith Hour of $5 beers, wines and appetizers to the weekend, it actually extends the hours to 3 to 7 p.m., as opposed to the 5-to-7 weeknight deals.

Mad Fox Brewing Company
Weekends are probably the only time city-dwellers can make it to Bill Madden’s great brewpub, and thankfully the happy hour specials — $2 off all of the house-brewed ales and lages — are offered from 3 to 7 p.m. on weekends as well as weekdays.
