• New York magazine’s Grub Street reports that Marco Canora and Paul Grieco have left Insieme, their very good restaurant in midtown’s Michelangelo Hotel: “The good news is this: Canora reveals to us that he has signed a lease at 24 Harrison St [next door to the Harrison]… and will open another, slightly larger Terroir there. About two-thirds of the menu will be the same as that of the East Village location, but new dishes are also planned. No opening date is set yet.” (You may know Canora and Grieco from Hearth in the East Village.) Pictured are three of Terroir’s winelists.

• Fighting words in the New York Times real-estate section: “Two real estate professionals, representing a 20-block area in northwestern Tribeca… have decided it’s time to secede from the neighborhood at large. They maintain that the northwest is distinguished from the rest by its warehouse architecture, lack of retail and office buildings, and cobblestoned streets. They are also selling real estate there.” Also, this: “‘There’s a lot of new development in Tribeca, and a lot of it leaves a lot to be desired,’ said Raphael De Niro, a managing director with the real estate brokerage Prudential Douglas Elliman Real Estate, who is marketing apartments at the Fairchild for $1,200 to $1,600 a square foot. ‘I feel like we should differentiate ourselves a bit.'”

• The Daily News spotted Ben Stiller “checking out 105 Reade St. He wasn’t looking at an apartment, either. He was on the prowl for the entire building. Priced at $14.5 million, the 50-foot-wide site between Church St. and West Broadway … is 16,000-plus square feet with additional air rights, meaning Stiller could build up if he wanted to. Built in 1860, the cast-iron, five-floor loft structure was designed by architect James Gilbert. Some of its floors have 16-foot ceilings. Just before going inside, Stiller was chatting up Kate Winslet, a Tribeca resident, outside the restaurant Sazon, the property’s only current tenant. With all that space, Stiller could house a production company in the building, which has a formidable facade.”

• The Jackie Robinson Musuem, slated for the northwest corner of Varick and Canal, has pushed its debut back to 2011, says Downtown Express.

• The Battery Park City Broadsheet Daily newsletter looks at how “Lower Manhattan parents are girding for a fight over who will attend grades six, seven and eight at P.S./I.S. 276, the school being built on Battery Place, when it opens in the fall of 2010.” Also, there’s a long letter about West Thames Street Park from Jeff Galloway, chair of the West Thames Park Working Group and co-chair of CB1 Battery Park City Committee.
