The end of Grace, a sleek, modern Chicago restaurant with three Michelin stars and a reputation as one of the nation’s best, was quick and messy: The chef, Curtis Duffy, and the general manager, Michael Muser, abruptly stopped working there in December 2017 after a dispute with their business partner. Two days later, Grace unceremoniously closed its doors.

The aftermath, though, has been more deliberative. As Mr. Duffy and Mr. Muser sparred with their former partner in several legal disputes and waited for their noncompete agreements to expire, they planned their next restaurant. It would have the best china, they said, the best furniture ever. They’d use ingredients that were fresher, more seasonal than they ever had before. They’d make a meal more elaborate than anyone had ever seen.

Ever: That word just kept coming up. So, they decided, that would be the name.

“It’s this little word, this little four-letter thing that we pack into the most epic experiences of our lives,” Mr. Muser said in a phone interview. “This experience, that we’re going to put in front of everybody, this is our Ever.”

Ever, scheduled to open next spring, will be in Fulton Market, a former meatpacking district that now houses culinary and cultural attractions. The restaurant, in a 6,000-square-foot ground-floor space, is being designed by Lawton Stanley Architects, the firm that also designed and built Grace. Ever will seat about 75 people in the main space, with a private dining room for another 12.
