Moonlight Roller Rink
From The Big Bang Theory Wiki
A roller rink in Glendale, California. Raj found out that there was a disco night there and suggested to the guys that they all go. Howard and Leonard, however, immediately made plans to go with their girlfriends, thereby cutting Raj out of it. He groused and complained until finally Howard took him skating there.
NOTE: The Moonlight Roller Rink is a real place, converted to a roller skating rink from a WWII aircraft factory in the 1950s. The shoot at the Moonlight was the first actual location shoot of the series, according to Bill Prady's twitter feed ("moonlight was our first actual location shoot. Told the place hasn't changed since it opened in 1951 or something." Tweet dated 1 February 2010).
