The Old Dairy
As of 03/05/17 only Nando's is open on the old Dairy Site. A Cineworld, Asda, Frankie and Benny's and other restaurants are all due to open over the coming weeks and months. South Ruislip rail and underground station (Central Line) are a couple minutes walk away just round the corner.
As of 03/05/17 - There's going to be parking specifically for the Old Dairy site, but this is not yet open, so park at the (free) Aldi/B&M car park next door. We can only assume it will be free off charge for up to 3 hours when it opens... but we'll have to wait and see.
