Seemingly replacing Whites Delicatessen (Whites Deli), a new wine and tapas bar is opening up under the railway arches. Platform 3 Chelmsford, 27 Viaduct Road, Chelmsford, Essex CM1 1TS. Their telephone number is 01245 926126. You can find the location of "Platform 3 Chelmsford" on OpenStreetMap.
This place is apparently under the same management as the Monnis Greek Restaurant nearby. However there is still apparently a lot of work to be completed before it can open tomorrow (Friday 8th March 2013, 5pm). Let's see if they can meet their timetable.
