Here's 6 options:
The Green Monsta. A popular version consists of two parts Pernod Absinthe, one part simple syrup, and a splash of soda water, served in a martini glass and topped with mint leaves. You can try it at Red Sky Restaurant and Lounge (16 North St., Faneuil Hall/Government Center).
The Boston Cooler. According to The Fine Art of Mixing Drinks author Dave Embury, this drink is a Horse's Neck with a kick. Mix 2 oz. rum, 1/4 oz. simple syrup, 1/2 oz. lemon juice, and soda water or ginger ale. Shake the first three ingredients, and serve in a highball glass garnished with a spiral of lemon or orange peel.
The Ward Eight. Also known as The Ward 8, this most famous Boston cocktail originated in 1898 in Boston at the bar of the Gilded Age restaurant Locke-Ober, according to San Francisco-based bartender Jennifer Colliau, and is still served there, too (3 Winter Place, Downtown Crossing). Combine 2 oz. rye whiskey, 3/4 oz. fresh squeezed lemon juice, and 1/2 oz. real pomegranate grenadine. Shake and strain into a (preferably chilled) cocktail glass.
Boston Sour. Drink (348 Congress St., Fort Point/Innovation District) is menu-less, but the bar serves the best kind of its namesake. Their Boston Sour recipe first appeared in Burkes Complete Cocktail and Tastybite Recipes in 1936: Pour 2 oz. rye or bourbon, 1 egg white, 1/4 oz. simple syrup, and 1/2 oz. lemon juice into a Collins glass and fill with soda water.
The Bostonian. Its a drink for both gin lovers and haters. I'm not a huge fan of gin, but when this is done right, it's delicious, said Boston resident John Galvin. It's made from 1 1/2 oz. gin, 3/4 oz. Italian vermouth, and 1/2 oz. lime juice, and typically garnished with a pickled onion.
The Boston Mule. This cocktail varies from location to location, but it's always sweeter than the name makes it sound. Woodward's (1 Court St., Faneuil Hall/Government Center) makes an attractive version with Absolut Wild Tea, AJ Stephans ginger beer, and spearmint leaves.
