The popular Hell's Kitchen Greek eatery Uncle Nick's is planning to launch a new branch in the second week of May at the corner of 29th Street and Eighth Avenue, right near the Fashion Institute of Technology. The new branch will be Uncle Nick's second attempt at expansion. The 17-year-old restaurant previously had a sibling in Manhattan from '97–'98 at 569 Hudson St. in the West Village. That space became Philip Marie, now in its 10th year of operation. And the location of the new Uncle Nick's branch has its own storied past. It was from 1974–2006 the site of a local institution: the now defunct old-school Spanish restaurant Estoril Sol (382 Eighth Ave.; 212-609-0500).
