NEW HAVEN — Celebrity chef Mario Batali may be expanding his restaurant empire to a 2,500-square-foot space at 278 Park Street.

His Batali & Bastianich Hospitality Group is seeking city approvals for a Tarry Lodge restaurant.

“The space was originally zoned for a 54-seat restaurant, which is really too small for our purposes,” says Tarry Lodge managing partner Nancy Selzer. “We need 74 seats. We’re also going to be seeking a restaurant liquor license.”

If all the hurdles are surmounted, Selzer adds, the new restaurant will be similar to the Tarry Lodge in Westport, which has a wood-fired pizza oven and is a “more casual style” eatery than the “fine dining” flagship Tarry Lodge in Port Chester, N.Y.

The Batali group is working with Yale, which leases 278 Park Street from St. Thomas Moore Corp.
