Ozone Coffee has four London locations - two full eateries in East London and two weekday espresso bars in the City. All four serve the same coffee programme: rotating single origins on filter, house blends on espresso, and seasonal batch brew.

Shoreditch and London Fields are full-service eateries with breakfast and lunch menus, open seven days a week. Both are committed to local suppliers and minimising waste - with as much attention paid to what's on the plate as what's in the cup. Walk-ins welcome at weekends; for groups of 7 or more, please email the eateries directly.

Ludgate Hill and Creechurch Lane are weekday espresso bars - coffee, toasties, and pastries, no table service. Both open Monday to Friday.

Well-behaved dogs welcome at all sites.

Booking info:

• On weekends, Shoreditch and London Fields operate on a walk-in basis during the day.
• For groups of 7 or more, please email the eateries directly.
