Organization, Consolidation and Presentation of Financial Statements [Abstract]

Shake Shack Inc. ("we," "us," "our," "Shake Shack" and the "Company") was formed on September 23, 2014 as a Delaware corporation for the purpose of facilitating an initial public offering and other related transactions in order to carry on the business of SSE Holdings, LLC and its subsidiaries ("SSE Holdings"). On February 4, 2015, we completed an initial public offering ("IPO") of 5,750,000 shares of our Class A common stock at a public offering price of $21.00 per share. We used the net proceeds from the IPO to purchase newly-issued membership interests from SSE Holdings ("LLC Interests"). Following the organizational transactions completed in connection with the IPO, we became the sole managing member of SSE Holdings. As sole managing member, we operate and control all of the business and affairs of SSE Holdings and, as a result, consolidate the financial results of SSE Holdings. We report a non-controlling interest representing the economic interest in SSE Holdings held by the other members of SSE Holdings. As of September 27, 2017 we owned 71.2% of SSE Holdings. Unless the context otherwise requires, "we," "us," "our," "Shake Shack," the "Company" and other similar references, refer to Shake Shack Inc. and, unless otherwise stated, all of its subsidiaries, including SSE Holdings.

We operate and license Shake Shack restaurants ("Shacks"), which serve hamburgers, chicken sandwiches, hot dogs, crinkle-cut fries, shakes, frozen custard, beer, wine and more. As of September 27, 2017, there were 143 Shacks in operation, system-wide, of which 79 were domestic company-operated Shacks, 10 were domestic licensed Shacks and 54 were international licensed Shacks.
