Black Milk Gastro Bar is an omakase-style restaurant. Guests do not order from a menu; smaller dishes arrive one by one, so the meal follows a sequence set by the kitchen. Visit Stockholm says the cooking draws on influences from around the world and uses a mix of techniques and flavours. Cocktails are the main pairing, rather than wine or beer.

The restaurant's website lists opening hours as Tuesday to Thursday, 18:00 to midnight, and Friday to Saturday, 18:00 to 01:00. Visit Stockholm gives the address as Engelbrektsgatan 3, while the restaurant's own site lists Birger Jarlsgatan 32 in Östermalm. Confirm the location when reserving. Visit Stockholm lists the phone number as +46 8 611 80 18.

The restaurant's website lists Best New Cocktail Bar from the Bartenders' Choice Awards in 2024 and Very Fine Level from White Guide in 2024. It also says the restaurant is listed in the Sweden Michelin Guide for 2026. The site has a reservation link and a page for a private room. The format suits guests who want dishes served as a progression rather than choosing separate items from a menu.
