In 2011, when Sam Mink and Anthony Padilla bought the loft where characters played by Tom Hanks and Antonio Banderas had lived in the 1993 movie “Philadelphia,” there were many things they liked about the space.

“We were totally wowed,” said Mr. Mink, 49, an owner of the Philadelphia restaurants Oyster House and Mission Taqueria. “It had a roof deck and open floor plan,” plus a ceiling that rose to 16 feet.
