It was a Bodacious Burger Bonanza.

And those bypassing the former Post Office downtown were bombarded midday Tuesday with burger deals awfully hard to resist -- free! -- compliments of Plan B Burger Bar, which hopes to open its seventh restaurant in the landmark building by fall.

The promotion, a natural since it was also National Burger Day, was staged by a crew from Plan B Burgers, who set up a tent and burger truck next to the former Post Office at 1262 Post Road, where the restaurant plans to renovate space for a restaurant to add to its five others in Connecticut and another in Massachusetts.

Plans call for the Fairfield Plan B Burger Bar to open by fall, if final zoning permission is granted and renovations proceed according to the current schedule.

"Free cheeseburgers! Get your free cheeseburgers!" yelled Rachel Hurvitz to passersby. "Not only is it National Burger Day, but also (former) Governor Jodi Rell proclaimed May 28 as Plan B Day in Connecticut in 2009," she told the Fairfield Citizen. Hurvitz was accompanied by Kyle Farewell, dressed as the restaurant's mascot, "No Pink." The name refers to the way customers can order their burgers: "some pink" or "no pink."

The closest Plan B to Fairfield is in Milford at 1638 Boston Post Road. In addition to an array of burger choices, the Plan B menu includes soups, salads and appetizers.
