People having a hard time deciding what to have for dinner from Fairfield’s burgeoning menu of dining options, now have a “Plan B” — the restaurant that features beef, burgers, bourbon and beer.

The state-based chain, which now has six locations in Connecticut, officially opened to the public Monday in the former U.S. Post Office building on the Post Road. In addition to the state restaurants, there are also Plan B outlets in Springfield, Mass., and Washington, D.C.

“We’re very excited,” manager Scott Pepe said. “It’s been a long time coming.”

Two years, to be exact, as renovations to the property took that much longer than initially expected to complete. All but the facade of the former postal building, constructed in 1936, was demolished. The facade has been incorporated into what will be a multi-tenant commercial structure. Plan B is the anchor tenant.

Pepe said the restaurant is now fully staffed, trained “and ready to go.”

It might be hard to tell from the street, however, since the restaurant’s permanent sign isn’t up yet, though Mike Russo, the general manager, expects it to arrive soon.

He said a private party to mark the restaurant’s opening was held last Friday night.

The restaurant is known for its fresh beef, ground in-house twice a day, and no pre-formed or frozen burgers. It also has a selection of all-natural, boutique bourbons and American craft beers.

Plan B Burger Bar, 1262 Post Road, is open 11:30 a.m. to 10 p.m. for kitchen service, and until 1 a.m. for the bar, Sunday through Thursday. On Friday and Saturday, the kitchen is open until 11 p.m. and the bar until 2 a.m.
