A decade ago, the East Village’s offerings were sparse: an old-school Greek restaurant, an ’80s-era gay bar and little else. Now its historic brick buildings — and shiny new ones — also host a grab bag of tasteful restaurants, stylish boutiques and quirky businesses, from hip antiques, stationery and kitchen stores to a snarky T-shirt store that recently opened in a bigger space next to a decadent ice cream sandwich shop. Dozens of apartments and condos are also adding to the neighborhood’s mix.
