I've been super-busy lately or else I would have posted this sooner...so, the River Palm, specifically the Mahwah location, has been sold to Frank Gashi and Patriot Gjonbalaj. Various reports say that the plan is to make the restaurant into a "classic New York steakhouse" and they plan on some immediate changes. A bar menu will be offered for the first time, as well as offering new, specialty drinks, some of which will be paired with the new bar menu. I don't specifically remember a bar menu per se, but I thought I remembered at various times they had "specials" and/or smaller offerings at the bar, similar to a "bar menu." I really don't remember because even when I sat in the bar area, which is fairly often, I always ordered off the regular menu.
The new owners have a 20 year history in the business, and most recently were running Il Mulino Prime in NYC.
