Just checked, Uber still lists HK.

Does Grab operate in HK?

My only experience with those red cabs was that it stinker inside and I think I paid about 80 HKD to get from Hong Kong station to Wanchai.

Last time I went to HK, in 2017, I used Uber a couple of times. Both really nice cars, including a Mercedes sedan. In fact I did the latter for a short ride, from TST to the Air Express station and the fare was only about $3-4 USD. The driver was disappointed at the short fare but that's what I clearly indicated in the app. She wanted to know if I wanted to go to the airport but I had a return ticket on the train.

I think I was in Soho when I checked the app. to go up to Victoria Peak. It showed about $65 HKD but it ended up about twice that. Still not too bad.
