I think that's the point! I found some possible candidates on Google Street View (which only has isolated spots):

From Chobhar in March 2019, facing Everest: https://www.google.com/maps/@27.6541403,85.2796492,3a,75y,78...

Elsewhere in Kathmandu in April 2020, facing Everest: https://www.google.com/maps/@27.6745306,85.3249687,3a,75y,59...

There's no hope of seeing that far through the haze.

It looks like if you get out of the valley itself, you can see Everest from a nearby hill on which there's a viewing platform of some sort.
