Haven't made reservations for New Year's Eve yet? Want to go out with your friends without dropping serious money for an open bar or a black tie-optional ball? That's not a problem at these bars, which will be open without cover charges or the need to call ahead. Just remember to show up early if you want a seat or to avoid lines.

Since nothing says "New Year's Eve" like champagne, 2 Birds 1 Stone has a menu of cocktails made with sparkling wine, including one called Yr Next (High West Silver Whiskey Western Oat, coconut, passion fruit and champagne, $16) and a bubbly punch ($12). All cocktails are priced a la carte, and no reservations are taken. 1800 14th St. NW.

The Truxton Circle cider bar is open as usual with reservations for New Year's Eve. At midnight, the staff will tap a free-flowing barrel of Basque cider known as a Txotx, and everyone drinks their fill until it's gone. The kitchen will stay open later than usual, because what's a glass of free cider without a snack? 300 Florida Ave. NW.

Bar Pilar is going for both ends of the New Year's Eve spectrum: The upstairs dining room hosts a seven-course, $75 tasting menu, while the downstairs bar will be open as usual with a limited menu. Tables will be cleared for dancing to a DJ around 11:30 p.m.; everyone receives a free sparkling midnight toast. 1833 14th St. NW.

Dance to the funky sounds of the Experience Brass Band from 10 p.m. until last call, interrupted only by a midnight champagne toast. 2002 Fenwick St. NE.

It's business as usual in Bloomingdale with a DJ and a midnight "champagne of beers" toast with pony bottles of Miller High Life. 116 Rhode Island Ave. NW.

The subterranean Glover Park bar has pool, shuffleboard and a DJ spinning '80s, hip-hop and soul tunes from 8 p.m. on. Everyone gets a free toast at midnight. 2233 Wisconsin Ave. NW.

It's just like any other Saturday night at Cafe Saint-Ex, with DJ Rene playing dance music in the basement. 1847 14th St. NW.

Both branches of the Capitol City Brewing Company will be open with no cover charge on New Year's Eve. In downtown Washington, look for beer specials from 10 p.m. to 2 a.m. and a midnight champagne toast; the Shirlington brewery has dancing with DJ Lyric, dinner specials and a midnight beer toast. 1100 New York Ave. NW; 4001 Campbell Ave., Arlington.

DJ Ameer Dyson (of Oddisee's Good Compny touring band) provides the tunes at the low-key Brookland bar, where there's a free midnight toast. 2801 Eighth St. NE.

The Fairfax location of Dogfish Head features a 9 p.m. performance by the Joint Chiefs, a local group that covers Steely Dan and the Allman Brothers. An optional dinner with beer pairings is available, and everyone receives a free Dogfish Head champagne glass at midnight. 13041 Lee-Jackson Memorial Hwy., Fairfax.

DJs CorTzu and Stevie A -- veterans of the long-running Lemur Lounge and Soul Monkey nights -- spin underground hip-hop, soul and funky breaks beginning at 9 p.m. The full menu will be available until 11:30 p.m., followed by special late-night burritos and tacos. 108 Rhode Island Ave. NW.

While Jack Rose is offering an early all-you-can-eat-and-drink barbecue fest on the roof and a $125-per-couple cocktail tasting in the basement Dram & Grain bar, the main floor will be open as usual with no cover or minimum. Expect special menus with tasting flights of vintage spirits and whiskeys. 2007 18th St. NW.

The end is near for the three wildly popular Christmas-themed bars, which close for the year on New Year's Day. Brave the crowds one last time between 3 and 9 p.m. for drink specials and general post-holiday fun. 1843 Seventh St. NW.

DJs Lemz and Vodkatrina provide pop dance music from 8 p.m. on, with a free midnight champagne toast for all. 900 U St. NW.

Arrive before 9 p.m. to avoid the $20 cover, then spend your night drinking special cocktails -- think Manhattans made with fancy rye whiskeys -- or dancing to a DJ in the upstairs bar. 1539 Seventh St. NW.

The final Literary Cocktails night of the year finds veteran bartenders Chantal Tseng and Dan Searing creating drinks inspired by post-apocalyptic fiction, including Cormac McCarthy's "The Road" and Margaret Atwood's "Oryx & Crake." Many of the drinks will involve fire, Tseng says in an email, "because 2016 deserves to go down in flames." Doors open at 7 p.m. 829 Upshur St. NW.

There are two themes under one roof at the Red Derby's Decades of Decadence party. The main floor will be dedicated to the 1990s, with a playlist featuring the Mighty Mighty Bosstones and Smash Mouth (among others) and Surfer on Acid cocktails, while the rooftop is a Studio 54-inspired mix of Earth, Wind and Fire, the Bee Gees and Harvey Wallbanger drinks. Both bars will sell $4 glasses of bubbly and $2 Kamikaze shooters, and everyone gets a free midnight toast. Parties of six or more can email bar@redderby.com to reserve a table, which includes a free bottle of sparkling wine. 3718 14th St. NW.

One of the top places to find cocktails for $10 or less, Service Bar is throwing a similarly wallet-friendly New Year's Eve: There's a regular menu and no cover. The U Street bar will be serving breakfast from midnight to close, and if you buy a full bottle of champagne -- say, a $69 Perrier Jouet Grand Brut -- your food is free. 928 U St. NW.

The usual dinner menu will be available at Shaw's Tavern, with the addition of magician Kourosh Taie, who will be performing tableside from 8 to 11 p.m. A DJ spins from 9:30 p.m. to 1:30 a.m., and everyone receives a glass of champagne at midnight. 520 Florida Ave. NW.

DJs Tara Robles, Tim Reaper and Sean Saley spin punk and metal tunes all night with no cover charge. An optional $50 open bar ticket, which can be purchased at the door, includes unlimited beers and whiskeys, as well as a burger. 201 Upshur St. NW.

If you want to get classy without paying an exorbitant fee for dinner or an open bar, consider the Watergate's Next Whiskey Bar, which will be open as usual. 2650 Virginia Ave. NW.
