Hidden in a dark corner of New York City’s Grand Central Station sits a luxury cocktail bar and lounge doubling as one of the city’s historic landmarks. For a year it was shuttered, but now the Campbell Apartment is open to serve the public again, Travel+Leisure reports.

The location was once the office of early 20th century railroad executive John W. Campbell during the 1920s. After serving as the location for CBS Radio and as a small jail for Metro-North Railroad, the space was converted into a bar in 1999. Then, in 2016, the Campbell Apartment—with its high ceilings and faux stone fireplace—closed when previous owner Mark Grossich lost his lease after 17 years of business.

Today, the Gerber Group runs the public bar that features signature cocktails; fancy finger foods, such as tuna tartare tacos and meatball sliders; and a casual dress code. The bar also has a view of Grand Central’s main terminal, as well as a terrace that faces a busy 43rd Street.

The New York Historical Society had to approve any interior changes because of the bar’s status in the city. “We wanted to make sure that we refreshed it but it’s such an iconic place and people have memories of it,” Scott Gerber, CEO of Gerber Group, explained to Travel+Leisure. “We wanted to make sure we were respectful of whatever we did."

The Campbell Apartment is now open at Grand Central Terminal at the corner of 42nd Street and Vanderbilt Avenue.
