Cinco de Mayo, Amigos!

In case anyone asks, the Cinco de Mayo holiday commemorates the victory — on May 5, 1862 — of the greatly outnumbered Mexican army over the French at the battle of Puebla. But most people will be too busy drinking margaritas to delve deeper. Instead, drink deeper, at the following locations:

El Centro D.F., 1218 Wisconsin Ave. NW

Georgetown’s Mexican outpost is putting out a $20 bottomless buffet, with tacos, enchiladas, fajitas, tostadas and churros. $6 margaritas and $5 Mexican beers.

L2 Lounge, 3315 Cady’s Alley NW

Doors open at 6 p.m. for a night of fundraising to support the victims of the earthquake in Ecuador. Happy hour specials, party favors and a DJ spinning Latin music.

Malmaison, 3401 Water St. NW

Malmaison DC and promotional partner IgniteDMV present a Cinco de Mayo Experience with a sangria bar, delicious food and desserts, stilt walkers, a mariachi band and a DJ. Tickets are $25. For tickets, visit eventbrite.com.

Morton’s The Steakhouse, 3251 Prospect St. NW

A Casa Noble brand ambassador will be at Morton’s for a Make Your Own Margarita & Tequila Tasting. Tickets are $60. For tickets, visit eventbrite.com.

And this Saturday…

Running of the Chihuahuas, The Wharf, 600 Water St. SW

Watch 96 chihuahuas race for the finish line as you sip a Mexican beer and order from food trucks between 1 and 4 p.m. All proceeds from the race will go to Rural Dog Rescue, a group that saves dogs from high-kill shelters.
