Info from Wikipedia
Larry's Hideaway was a bar in the Prince Carlton Hotel in Toronto, Ontario, Canada. The venue was notable for being one of the first venues in Toronto to open itself to punk and new wave music acts, as well as hard rock.
The bar was located in the basement of the Prince Carlton Hotel on the north-west corner of Allan Gardens, on Carlton Street at Jarvis Street. The room was a restaurant prior to 1961, when it became a jazz venue.
The bar closed in the summer of 1986, but the hotel remained open. The hotel was sold in 1988 and closed. It was boarded up and left vacant. On October 16, 1991, a three-alarm fire destroyed much of the hotel. The City of Toronto government bought it in 1990 to increase the size of Allan Gardens park. The location is now the off-leash dog area of the park.
