"The famed French restaurant La Grenouille has been closed since June when it shuttered due to a gas leak. (It briefly reopened in November.) The building at 3 E. 52nd Street, near Fifth Avenue, where La Grenouille has operated since 1962, is now up for sale with an asking price of $15 million, Curbed reports. In recent years, the original owners’ sons, Charles and Philippe Masson, have been engaged in a bitter feud over control of the restaurant. Charles, the manager for decades, stepped away from the restaurant in 2014; Philippe has been running the business since then." - Luke Fortney
