Previously Flowerhouse, this is now The Hart operated by Public House Group. It's right next to Chiltern Firehouse, closed because of fire damage at date of this entry. Note that there is no named fascia on the exterior of the pub and no name on the swingsign.

There is a pub on the ground floor with an authentically pubby look, serving British beers such as Portobello Pilsner, Allsopp’s and DEYA. There are two cask ale handpumps. Bar snacks and a full menu are available all day. The first floor has an open kitchen, the second floor a restaurant; and the third floor is described as "an intimate dining space". The menu at The Hart contains British pub classics made with ingredients from British farmers and producers; fresh produce comes from their own market garden at Bruern Farms.

No bookings taken, walk-ins only. PHG targets its market via influencers and social media and the cord outside the pub corrals the waiting crowd. The pub has been reviewed as "good cooking, great ingredients, attentive service, decent drinks, and a lovely aesthetic".
