Ever since Parnell’s Irish Pub opened three years ago in Playhouse Square at 1415 Euclid Ave., it has been a hotspot for the working crowd, serving up perfect pours of Guinness Stout and a selection of 90 whiskeys and bourbons. The pub has been so popular that owner Declan Synnott decided it needed more room, so he bought the vacant restaurant space next door and began building an 800-square-foot addition in January, which is expected to open later this month.

“It turns out business is better than I thought it would be,” Synnott says. “What we really need now is just more space so people can be more comfortable.”

The original Parnell’s Pub opened in Cleveland Heights in 1995 after Synnott moved to the city from his native Dublin, Ireland. He opened his second location in Playhouse Square in March 2013 to take advantage of the area’s nightlife scene. The upcoming extension, Synnott suggests, takes influence from the recent development on Euclid Avenue.

The renovations, which were carried out by Turner Construction, were funded by Synnott and Playhouse Square. His wife, Liz, did the interior design, the majority of which features repurposed items. For example, the extension includes a 250-square-foot private room with an 18-foot-long U-shaped table made from old church pews. Light pendants fashioned from old bourbon-barrel wood and sconces made from the barrel’s aluminum wrap illuminate the space. They also rescued barn doors from an old downtown firefighter training facility, which they are using to section off the room.

Parnell’s is slated to host live bands and folk sessions in the new space by September.

Adding three new employees and space for about 45 additional patrons, Synnott is sure adding the new space was a no-brainer, especially because he estimates as many as 4,000 people on any given night descend on the district’s five block radius.

“It’s nice being shoulder-to-shoulder,” Synnott says, “but I want my patrons to be, first of all, comfortable, you know? That’s the atmosphere we’ve projected since we started [in Cleveland Heights] 19 years ago: a place to go after a hard day’s work.”

While Synnott planned for a St. Patrick’s Day finish, city permit delays – due to construction projects for the RNC – pushed completion to a late March opening, but Synnott, who’s awaiting his second child, isn’t too bothered by missing the St. Patrick’s Day goal.

“Would I like the space done? Yeah, of course,” he says. “But one day ain’t going to make us or break us.”
