Brian O’Donnell and Dropkick Murphys frontman Ken Casey have had a busy few years, renovating Lower Mills Tavern while opening Yellow Door Taqueria and Lion’s Tail and also tending to McGreevy’s. Now for their next project with partner Chuck Hitchcock, they’re not content to open simply one restaurant—they’re prepping a two-in-one spot. Dual concept Two Saints Tavern and Dos Diablos will combine the elements of a beer hall with a Mexican-inspired eatery when it opens in the Symphony neighborhood in May.

“We had a unique opportunity with this space to be able to do two different concepts with how it’s split up,” Hitchcock explains. “We wanted to have a little bit of a fun dive bar feel on one side for the kids and also provide something for the local residents and people who are looking for more of a restaurant.”

Setting up shop in the former Our House East, the approachable, laidback atmosphere of the beer hall is expected to act as a stark contrast to the dark, elevated taqueria side, described by Hitchcock as having an “almost religious feel” with black chandeliers hanging from the ceiling and a stained glass motif behind the bar. 

Chuck Hitchcock says Dos Diablos will serve cocktails such as the Oaxaca Old-Fashioned.

“It’s kind of the cross between good and evil,” Hitchcock says. “How do you want to go today? Do you want to be good and be on the beer hall side? Or do you want to get a little more risqué?”

Both sides will serve food and drinks seven days a week, with the beer hall opening at noon and Dos Diablos opening at 4 pm. The taqueria menu features sections for apps, ceviche and tacos like the pork carnitas made with crispy pork confit, queso chihuahua, salsa verde, black bean puree and crema. The cocktail menu will include libations like the Sparkling Cyanide, combining Beefeater gin, green Chartreuse, dry vermouth, Alessio blanco vermouth and a splash of sparkling rosé in a classic coupe. To accompany Two Saints’ eight beers on tap, the menu will consist of small bites and bar food, with options like jumbo salted pretzels served with a choice of sauces and heartier fare like a chicken Parmesan panini.

Possessing a full entertainment license and capacity for 287 people—with seating for 58 in the taqueria and 18 in the beer hall—Hitchcock hopes this latest endeavor will serve sinners and saints alike.

“We’re trying to create a fun atmosphere for the local clientele where they can come in and hang out in between classes, get a great dish of food or just sit down and have a great cocktail at the end of the day.” ◆
