The new Millennium Centre condominium tower in Chicago’s River North neighborhood has landed two upscale eateries that will take up more than half of its 26,000 square feet of retail space. Developer C.A. Bud Cataldo, who owns the retail portion of the 33 W. Ontario St. high-rise, said he has leases signed with Erv Emery, the local franchisee of national fondue restaurant chain Melting Pot, and Kevin Nierman, who plans to open a second location of his popular Deerfield restaurant Masck.

Lease terms were not disclosed. Mr. Cataldo, who is chairman and CEO of Schaumburg-based hotel management firm Hostmark Hospitality Group, said both restaurants will open by June.

“We wanted to get just the right mix of restaurants in that space,” he said. “Both of them have a record of being very successful.”

Millennium Center will be home to the first Chicago locations for Melting Pot and Masck. Florida-based Melting Pot has nearly 70 sites in the U.S., including three in the Chicago suburbs of Buffalo Grove, Oakbrook Terrace and Schaumburg. Entres range from $17-$19 and fondue combination dinners start at $48.

The owners of Masck, meanwhile, have just one location in the Deerfield Commons shopping center. Mr. Nierman, who co-owns the contemporary eatery with his wife, Michelle, said they were looking to expand into the city when approached earlier this year by Mr. Cataldo’s partner, William Marovitz.

“It’s a great space right on the corner of Dearborn and Ontario,” Mr. Nierman said of the restaurant space. “We saw it as a perfect opportunity for our restaurant.”

Masck features American classics like steak and seafood.

Neither restaurant owner would disclose revenue projections for their Millennium Centre sites.

Millennium Centre already is home to a Cold Stone Creamery ice cream shop, which opened in September, and a Bank of America branch. Plans are underway for a Subway sandwich shop and tanning salon.

With Melting Pot and Masck, Millennium Centre’s ground level and concourse retail space is fully leased.

The 60-story condo tower, developed by Chicago-based American Invsco Corp., is about 94% sold, with units ranging in price from the high $300,000s to more than $2 million.
