This has now become a Zero Waste shop called Liberte Cherie

Old 1:2500 map (https://maps.nls.uk/geo/explore/#zoom=20&lat=51.54613&lon=-0.20329&layers=170&b=1) has this terrace of shops as being from 385 to 401 with 2 narrower shops. Looks as though two numbers apply to flats above as there are two entrances visible in Bing Streetside. 391 is correctly assigned as FHRS has the Wood Pizza place & it is visible on Streetside. 405 (Tesco) is called Malcolm House (NROSH Data0.

There's a footway mapped on a bridge here that doesn't exist. I'm fairly sure the bridge carries electricity cables over the canal to Amberley Road substation.

Needs survey, but according to a Camden Council open dataset on polling stations, we're missing a "Mortimer Crescent Tenants and Residents Association Hall" around here: http://harrywood.co.uk/maps/map-my-data2.html?url=https%3A%2F%2Fopendata.camden.gov.uk%2Fresource%2Ftdwv-zwut.json
