Insomnia Cookies Opening First Brooklyn Outpost in Park Slope, the Commercial Observer reported 6/13/19.

That''s quite an evolution for a once-humdrum building at 32 Fifth Avenue, the southwest corner of Fifth Avenue and Dean Street, adjacent to Yayo's Latin Cuisine and now close to the Barclays Center.

According to the article, the bakery chain has a 10-year lease for one of the two ground-floor spaces at the double-wide three story building, which was marketed for $7.5 million, sold for $6.6 million in November 2015, and then went through a $3 million gut renovation. Such spending means they're not looking for mom-and-pop businesses.

(The previous loft owners were bought out in August 2013 for a collective $5 million, if I'm reading the city's property records correctly.)

Though asking rent exceeded $150 per square foot, according to the article, no contract rent was announced. Shake Shack and other new food purveyors are nearby. According to Bklyner last month, a new owner will be reopening Yayo’s next door, given rent increases, while its former owners have moved down the block to establish a smaller restaurant, Besito.

The 32 Fifth building through the years

As of June 2011, according to Google Street View, an accountancy firm was in the ground floor.

As of October 2013, H&R Block was a (former) tenant, according to (ghost) signage.
