Being underground in NYC is no longer a necessary evil.

TurnStyle, the Chelsea Market-esque collection of 38 restaurants, food stores and retailers, opens to the public on Tuesday, April 19, at 5 p.m. Two years in the making, it's transformed a disused corridor beneath Eighth Avenue leading to the 59th Street-Columbus Circle subway stop into an airy, modern industrial market.

It's meant to feel like a street in the city, according to lead developer Susan E. Fine, and it accomplishes that with Insta-worthy mosaics on the floor and walls, brightly lit ceiling alcoves, elegant grating to hide the guts of the station and generally looking like a 21st-century subway corridor should look. Unlike the cold, stately affair that is the World Trade Center Hub, TurnStyle is inviting in the way that makes you crave custom doughnuts and sea salt hand cream. There's even wine and beer, courtesy of Ellary's Greens

The shops, most of them hand-picked by Fine (and often from personal experience as an Upper West Sider), are meant to cater to the half-commuter, half-tourist crowd of 90,000 who came through daily until last July, when construction began. There's live entertainment planned for the southern end of the corridor, with Lincoln Center first up.

Sorry, Columbus Circle commuters. You're about to have a lot of company.
