The original Billy Goat Tavern opened in 1934 across from what’s now the United Center before moving to its current flagship location on Michigan Ave in 1964. Since then, the tavern has expanded with multiple locations around Chicago. It rose to fame in the ‘70s when Billy Murray and John Belushi spoofed it and its infamous “cheezborger” on Saturday Night Live. Served on a Kaiser roll, the cheeseburger is the simple union of a thin, griddled patty, American cheese, and sandwich pickles. Pro-tip: make it a double.
