2 ATM Santander

From name & website I would expect that this is much more a restaurant than a pub

Car Parks of businesses along this service road look rather overgrown.

Restaurant with another name here now on FHRS https://ratings.food.gov.uk/business/en-GB/1280102

There's a football pitch visible here on Bing

Another path leads across grass here, with a desire line cutting across in front of NRO to join it near Leisure Centre Club

Does this path run on the field margin (looks like it from aerial imagery)? Hedges/fences would help a lot round here.

This site is a) no longer a hospital; b) called The Wilson. I worked here in 1991 when most of the buildings were offices for the then District Health Authority (Merton & Sutton). There may have been some health functions on site: it certainly sustained a canteen which suggested more people on site than just the DHA staff. Lost Hospitals of London (http://www.ezitis.myzen.co.uk/wilson.html) suggests that it currently hosts a range of clinical services, so amenity=clinic is probably more appropriate.

Cookham Tandoori now Spice Merchant (as name:en has it).
