The most romantic restaurant in Chicago must be Marie's Pizza & Liquors on the Northwest Side in Albany Park. This must be true because they have heart shaped pizza. And you should know the importance of heart shaped pizza.
Yes, other restaurants have heart shaped food for Valentine's Day, but none have lasted 73 years. Originally opened in 1940 by Theodore Karavidas as a tavern and packaged goods store, it wasn't until 1950 that Karavidas' son George added pizza. Marie's was named after Mary Karavidas, Theodore's wife and George's mother. If that's not love, I don't know what is.
