Hookah lounges are mostly found in college towns and urban areas and are regarded by some as a novel and chic way to socialize and embrace multiculturalism. Some people of Middle Eastern or South Asian extraction consider them a continuation of their own cultural traditions. A hookah and a variety of tobacco products are on display in a Harvard Square store window in Cambridge, Massachusetts, United States. Often, hookah lounges are owned and operated by people from the Arab world, origin and or other regions where use of the hookah is a centuries-old tradition. Some offer Middle Eastern cuisine menu items. Almost all offer what most Westerners call Turkish coffee. Many hookah lounges incorporate such elements as Islamic decor and Arabic music or Indian music. Typically a disposable mouthpiece is provided for each user for hygiene reasons. Hookah lounges do not typically have liquor licenses but instead derive the bulk of their revenue from sales of coffee, tea, soft drinks and snack foods. Some hookah lounges have well-equipped kitchens and are more akin to bistros. In the broadest sense, any restaurant or nightclub can be considered a hookah lounge if it offers patrons hookahs, shisha and a comfortable place to smoke. Due to several state anti-tobacco laws, many Hookah Bars have made the transition from smoking traditional shisha to smoking herbal shisha because it contains no tobacco, or nicotine and is legal indoors in areas specific to the prohibition of tobacco smoking. Herbs do produce tar when they burn.
