The Boardwalk's Cocoanut Grove conference center includes banquet rooms and a performing arts venue. Food, drink, and theater were profitable aspects of the resort since the original Casino of Swanton in 1904. Although gambling was never legal, it was generally known that guests could take boats from the "pleasure pier" to a ship in the harbor to play games of chance in the early days. During Prohibition from 1920 to 1933, serving alcoholic drinks was also outlawed and the casino changed its name to Cocoanut Grove. The name includes an old spelling of Coconut, "Cocos nucifera", which was used in the popular Marx Brothers movie "The Cocoanuts" of 1929. The name was also used by a number of popular nightclubs of the era, including one in The Ambassador Hotel in Los Angeles, California.
