Potomac Villagers were shocked this week at the sudden departure of River Falls Market, the 16-year-old gourmet store known for its fresh seafood and prepared meals. The store shut down without warning Sunday afternoon, a casualty of the bitter breakup between owner Jeff Grolig and his wife Ashley. The family also operated two neighboring restaurants, Renato’s and The Tavern, where it looks like business has resumed as usual. Enzo Iachetti, manager of Renato’s, says he’ll continue to run the restaurant under the direction of Ashley Grolig. At The Tavern, Jeff Grolig’s father has taken over day-to-day operations. “I haven’t managed the restaurant before, but I’ve been the owner since we opened it,” says John Grolig, a retired fireman and real estate agent. “I’ve got the same staff, and we’re going forward.”
