High Quality Content by WIKIPEDIA articles! The cuisine of Philadelphia was shaped largely by Philadelphia, Pennsylvania's mixture of ethnicities, available foodstuffs and history. Certain foods have become iconic to the city. Invented in Philadelphia in the 1930s, the cheesesteak is a well known icon of the city, and soft pretzels have become a part of Philadelphia culture. During the 18th century city taverns were major meeting places for politicians and businessmen while the 19th century saw the creation of two Philadelphia landmarks, the Reading Terminal Market and Italian Market. After a dismal restaurant scene during the 20th century, the 1970s saw a restaurant renaissance that has continued into the 21st century.
