Confirmed as Nextofficial, Oriel Brasserie who are in 2 terminals at Heathrow
Oriel Grande Brasserie and are opening for Easter, plus maybe Fiorella bags, Habiliments, Pinko, Dant, Insignia, Kurt Geiger and River Isle as they all appear on promotional material for the airport plus others. Enrique Tomas has opened or is about to open but I think they are in the old bit. Out of interest they flog chunks of ham. You can buy a whole ham from them for up to 225 Euros

Not sure how much the airport will benefit out of this but there will be additional services to Littlehampton and a new service to Rainham.
