RB’s Top 100 Independents ranking is a measure of the highest-grossing independent restaurants. Only restaurant concepts with no more than five locations are considered “independents” for the purpose of this list (although it’s possible a restaurant that shares a name with a chain but is owned and operated separately would qualify, such as Smith & Wollensky in New York City). Rankings are based on gross 2018 food and beverage sales. Information was gathered through surveys. When data wasn’t provided, sales were estimated based on public information, similar concepts and other factors.
