Walgreens disclosed its store plans last week. The other deals will be announced in coming weeks, according to sources involved in the deals who spoke on the condition of anonymity because the deals have not yet been formally announced.

YO! Sushi, founded in London in 1997, has more than 50 company-owned restaurants in the United Kingdom. The company describes itself online as having “brought the concept of a Japanese ‘kaiten’ sushi bar that delivered food to customers via a conveyor belt traveling 8 cm per second to the masses.”

YO! has no U.S. locations, but has been scouring neighborhoods including Georgetown, Dupont Circle and Clarendon, and now plans restaurants in Union Station and Las Vegas.

The Chinatown building, at the corner of 7th and H streets NW, is on one of the busiest pedestrian intersections in the city, adjacent to the Gallery Place Metro station and the Verizon Center. It was acquired out of bankruptcy by developers Douglas Development and McCaffery Interests, who quickly began marketing the project as Gallery Square to retailers.

Juan Cameron of McCaffery Interests and Norman Jemal of Douglas Development did not respond to requests for comment.

The Walgreens store will be its fourth in the District. That deal could deliver Douglas and McCaffery one of the highest rents per square foot in the District. One source involved in the deal said it would top $160 per square foot.
