While the days of trick-or-treating may be in the past for most staffers, that doesn’t mean adults can’t get in on the Halloween fun.

[IMGCAP(1)]Several bars and restaurants around town are rolling out creepy cocktails and spooky specials in honor of the holiday. So put on that costume and hit the town — here’s a list of where to partake in the festivities.

• Poste Moderne Brasserie (555 Eighth St. NW) is making over its “Poste Roast— into a “Ghost Roast— for Halloween. For $45 on Saturday night, guests can indulge in a three-course meal in the courtyard of the Hotel Monaco. The meal will include warm cider from the Eighth Street Market, pumpkin soup and salad, and wood-roasted baby goat, which will be spit-roasted in the courtyard. Guests are encouraged to wear costumes, and a five-course dinner for two will be awarded to the person who wears the best costume.

• Diners at Mexican hot spot Zengo (781 Seventh St. NW) will have the opportunity to choose between a trick or a treat at the end of each meal. Those who choose a treat will receive a complimentary dessert during their next visit to the restaurant. Those who go for a trick may walk away with a fun gift, or nothing at all. Tricks include a complimentary cocktail, dinner for two, a bento box — filled with several Latin-Asian dishes that are perfect for lunch — or nothing at all. The offer will run through Saturday with a limit of one per person.

• Capitol Hill’s Belga Cafe (514 Eighth St. SE) will be getting into the Halloween spirit with creepy cocktails. The bar will be mixing such festive cocktails as the Vampire Kiss Martini, made with vodka, champagne and Chambord, and the Blood Sucker Cocktail consisting of rum, pineapple juice and strawberry puree. Witches Brew Golden Ale direct from Belgium will be available for those who prefer beer to liquor. The Belgian eatery will also be passing out candy to local trick or treaters.

• Co Co. Sala (929 F St. NW) is offering boxes of Halloween-themed chocolate treats. Shell out $28 for a box of Burnt Mummies, a concoction of chocolate, peanut butter cream, salted dark caramel and crispy rice. Individual mummies are available for $6. Vampire’s Kiss Kupcakes — miniature dark-chocolate cupcakes with raspberry sauce — will be available for $4, as will chocolate and pumpkin seed brittle bark. The restaurant and bar will also open its Hot Co Co. Sips Stand from noon to 3 p.m. on Halloween.

• Mexican restaurant Oyamel (401 Seventh St. NW) will be celebrating the Day of the Dead through Nov. 2 with a special budget-friendly menu. No dish on the menu exceeds $8.50. In addition, there is a coupon for a complimentary cocktail available on the restaurant’s Web site. Patrons can start the meal with a Sloe Dead Fizz — a mixture of sloe gin, brandy, green Chartreuse, lemon juice and egg white — for $5. Entrées include an avocado salad and tamales.
