Four bars and nightspots are turning another year older this week. And unlike those friends who humblebrag about birthday plans on Facebook or drop none-too-subtle hints about how badly they'd like to get brunch at Le Diplomate soon, these businesses want to celebrate with no strings attached. Here's how you can get in on the fun.

Tuesday: Echostage turns one
The massive dance club is throwing itself two parties this weekend, with a sold-out appearance by Armin Van Buuren on Saturday and an intriguing pairing of BBC Radio don Pete Tong and former Swedish House Mafia member Sebastian Ingrosso on Friday. But the festivities actually begin tonight at sister club Barcode, where the 18-and-over Barcode Tuesdays feature an open bar and free hors d'oeuvres from 10 to 11, half-price bottles of wine and discounted bottle service. (Think $150 for a bottle of Belvedere or Stoli.)

Thursday: Le Grenier turns one
Cozy little Le Grenier still feels like a secret on H Street, albeit one with great happy hours and free monthly French wine tastings. Thursday's anniversary party kicks off with an open bar and passed hors d'oeuvres from 6 to 8, and includes $6 cocktails and a $10 tasting menu for the rest of the night.

Saturday: Smoke and Barrel turns two
The outstanding Adams Morgan beer-and-barbecue spot is sharing some rare and awesome beers on its special day, including Firestone Walker's Parabola Imperial Stout, the Bruery's funky Art of Tartness, a barrel-aged version of Sierra Nevada's Bigfoot barleywine, and Flying Dog's single-hopped Simcoe IPA. Ohio's award-winning Triple Digit Brewing Company, which is not usually available in D.C., is sending kegs of its Chickow double brown ale and Aftermath Scottish wee heavy. Here's the best part: Every beer, whether a rarity or a tasty Oktoberfest or pumpkin ale, is $5 from 11 a.m. until close.

Saturday: Rams Head Tavern turns 24
Annapolis' Rams Head Tavern is throwing a retro birthday party inspired by its 1989 opening date: '80s cover band the New Romance performs from 7 to 10:30 p.m., and there's an '80s costume contest with prizes for the best outfits. Arrive early for rad beer specials: draft beers cost $1 from 4 to 5 p.m. and $2 from 5 to 6, and domestic cans (served in an '80s-themed koozie) are $3 from 6 to 7. The rear parking lot will be tented for the occasion.
