Strangers - John Simm (2018) - Soundwill Plaza Midtown, Tang Lung Street

Jonah goes for a lunch with Xo's power hungry assistant, Rachel, and finds out why he recognises her. This looks as though it was filmed on one of the top floors of the Midtown building in Causeway Bay. There's a restaurant on the 30th floor called Penthouse with a balcony area that seems to fit the bill but, as always, corrections welcome.

Strangers - John Simm (2018) - VPoint Rooftop, Causeway Bay

Jonah meets with the Assistant British Consul to sort out the details of the accident and they head to a rooftop bar in Causeway Bay at the top of a fairly new building called V Point. I believe the venue is actually called "Alto" but knowing Hong Kong it will have changed a few months down the line to something else. This building is still so new (built 2016) that Google maps still has it marked down as (one of) its predecessor, Bloom House.
