Starbucks just opened Reserve in New York City, an upscale café where a 12-ounce cup of plain black coffee will go for $4—twice as much as the chain's signature Pike Place roast.

"This is not your regular Starbucks," one customer writes on Yelp. "This is Starbucks on crack." The store made its debut in a massive subterranean gallery space in the heart of New York's Chelsea neighborhood, according to Business Insider.

And of course, the store's interior—with color palette evidently inspired by coffee—is an art aficionado's dream.

The walls are decked out with artwork for purchase; the center of the store is a cozy lounge complete with armchairs, sofas, standing lamps and a vintage rug; hand grinders and other coffee accessories are on display around the store.

The menus—hand-lettered pieces of paper clipped to backer boards—include exclusive and rare coffees, with prices up to $4.50 for a medium serving.

The café is named after Starbucks' specialty coffee line—also called Reserve—and is one of 500 similar stores that the coffee giant plans to lunch globally over the next several years. [BI]
