Accountants pulled into dispute between investors in popular Chicago steakhouse

Estranged stakeholders in Maple & Ash — a Gold Coast steakhouse that’s the highest-grossing restaurant in the city — are asking a Cook County judge to enforce a subpoena against the Plante Moran accounting firm for documents stemming from the firm’s work for the restaurant.
