It may not be the last dance after all for Foxtrot, the upscale Chicago-based convenience store and cafe chain that closed abruptly in April before filing for Chapter 7 bankruptcy. Foxtrot co-founder and former CEO Mike LaVitola, backed by an investment group that purchased the chain’s assets in an auction last month, is planning to reopen about a dozen stores this summer, starting with the Gold Coast and Old Town locations in Chicago. The new company is also planning to hire back displaced Foxtrot workers, wherever possible, to staff the stores, LaVitola said.
