Feed the Yak opened on Friday (March 28), in Olympic Way, in Wembley Park.
In a post on Instagram the group said they were “delighted to start pouring beers”.
The company already has outlets in Elephant Park in Elephant and Castle, and an event space in Creekside, Deptford.
On its website, Feed the Yak said it will be serving craft beers, live sports on screens and food collaborations with different outlets, and all at “the foot of the world’s most iconic football stadium”.
The bar is a stone’s throw from Boxpark Wembley, which also has screens and runs events.
Feed the Yak! started life as the Tap In, housed in a shipping container next to the old Heygate Estate.
The company has been contacted for comment.
