Step inside these serious drinking haunts, if you dare.  

Black Cabin

Tucked inside the meat-centric restaurant Wild & Co, in the place that was once music and booze institution Stu-fe, Black Cabin Bar rekindles the live music spirit of its predecessor amid a moodily lit cabin vibe of dark red lighting and faux animals. The weekly schedule is packed: Tuesday is dedicated to blues, Thursday to folk and post-rock, Friday to experimental electronic house, Saturday to modern soul and Sunday to groovy jazz. Knock back craft beers or strong, frothy cocktails like the White Lies (Mekhong, Aperol, pineapple juice, syrup, lemon juice and egg white, B280), but be warned: everyone is expected to down a shot if someone rings the golden bell by the bar.
33/1 Soi Farm Wattana, Rama 4 Rd., 061-515-6989. Open Tue-Sun 5:30pm-1am

Dok Kaew House Bar

Taking over an 80-year-old, two-story house out the back of Phaya Thai, Dok Kaew House Bar not only boasts arguably the best selection of local craft brews this side of town, but also some excellent Thai food—to go with a few creepy claims that the house is haunted. Pick from an ever-rotating list of beers like Taopiphop Ale Project’s Hurtster Saison (B180), Yodbeer’s Bearnana Wit (B180) and Outlaw Brewing’s Outlaw Mosaic IPA (B180). Fiery food faves include leng (pork bone served with spicy soup, B130) and sai yaang (grilled pig’s intestines, B100) served with a tamarind-heavy jaew sauce.

71 Rama 6 Soi 28,  096-886-4104, Open daily 5pm-midnight.

Hair of the Dog

A former tap master at Mikkeller Bangkok runs this tiny bare concrete room filled with surgical lighting bar and hospital beds doubling as tables. The 13 rotating beers on tap focus on rare, exciting beers from the likes of Amager and Omnipollo. Expect to find drops ranging from Stone Ruination IPA to Mikkeller George Imperial Stout and Ol Yule Maelk (an imperial milk stout barrel aged on cognac and sherry barrels). There's a second branch in Phrom Phong, too. 
2/F, Mahatun Plaza, Phloen Chit Rd., 02-650-7589. Open daily 5pm-12am 

Hoay Bar

This semi-outdoor craft beer bar lives up to Chang Chui’s “sloppy artisan” theme with shabby leftover materials and old bits of machinery giving off a spooky scrapyard vibe. Making things even creepier, the frothy draft beers from local brewers are served through wooden grates that resemble those of Thai prison cells of yesteryear 
Chang Chui, 460/8 Sirindhorn Rd. Open daily 5-11pm

Ku Bar

Hidden far from sight in the Old Town, Ku Bar carries an alluring air of mystery. A dusty concrete staircase leads the way to a marble counter amid a decrepit room where Anupas “Kong” Premanuwat (who worked as a mixologist at New York’s acclaimed Angel’s Share), pours a monthly rotating cocktail menu that spotlights local ingredients plucked from the fresh market. Kong shows off fastidious attention to detail in the “10 Herb” (B360), which mixes jub liang herbal Thai tea with gin, honey, egg white, lime and burnt sugar.
3/F, 469 Phra Sumen Rd., 02-067-6731. Open Thu-Sun 7pm-12am
