Ratskeller (German: "council's cellar", historically Rathskeller) is a name in German-speaking countries for a bar or restaurant located in the basement of a city hall (Rathaus) or nearby. Many taverns, nightclubs, bars, and similar establishments throughout the world take the name Ratskeller.
The word had been used in English since the mid-19th century.
At least one New York restaurant called itself a "rathskeller" in the 19th century.
Notable Rathskellers in North America
The Boston, Massachusetts, Rathskeller (nicknamed The Rat) was a Kenmore Square live music venue that opened in 1974. It is notable for being one of Greater Boston's premier music venues for three decades and the starting point for the WBCN Rock & Roll Rumble.
The Ram's Head Rathskeller in Chapel Hill, North Carolina, was opened in 1948 by an Austrian Jew by the last name of Danziger, who came to Chapel Hill as a refugee from the Holocaust. "The Rat" was the first restaurant in the area to employ an entirely African-American staff. Long a popular spot with students and alumni, the restaurant, which extends over a catacomb-like basement with many different rooms, was filled with UNC memorabilia and history. "The Rat" was one of the oldest continuously operating businesses in Chapel Hill, but was closed down in 2008 due to non-payment of taxes. Its decor and memorabilia was auctioned off leaving just the bones of the structure. There were plans to reopen the restaurant under new management in early 2011, but dealing with, among other things, structural issues has delayed the project.
The Aztec Brewing Company in San Diego, California included a ratskeller as the tasting room at the brewery. Murals on the wall depicted various scenes of Aztecs painted by renowned Spanish artist Jose Moya del Piño. When the city tore down the structure, the murals were preserved for future use.
