Lahinch, the new restaurant moving into the Benny’s Bar & Grill space at Cabin John Shopping Center, will not be opening next month as originally planned. Owners Barry Nolan and Chris Hughes say they’re still finalizing their lease, with tentative plans to take over the space on New Year’s Day and open around the end of February. Lahinch, named after a famous golf course in Ireland, will offer a mix of locally sourced American-style dishes and traditional Irish entrées like lamb stew, fish-‘n-chips and corned beef with cabbage. Hughes knows his way around an Irish menu: He opened the Irish Inn at Glen Echo 12 years ago, and before that he ran the Four Provinces pubs in D.C. and Falls Church.
