Which is the nicest London pub for a wintery roaring fire pint?

Ideally more central than Hollybush

Which end of town.  Ye Olde Mitre (in Hatton Garden) or if you want fancy Scarfe's bar in the Rosewood. 

My fave pubs:

The Punchbowl

Hunter's Moon

The Cross Keys

The Cooper's Arms

The Grenadier and other little Belgravia pubs

Does the Cheshire Cheese still have that fabulous triangular cast iron coal burner in the middle of the ground floor bar?

+1 for the Grenadier

Antelope and Wellington on Eaton Terrace both v good.

The Dove may be a bit too far?

Highly likely it was a brothel bull, it's just off Covent Garden where most Inn's, Taverns and Ale Houses were connected with the trade.

I only learned recently that the light above the door of a pub was an indicator that the pub also operated as a boarding house and for your tuppence, you would get to share a bed with strangers (several).

Star Tavern, Belgravia

Grenadier also a good shout

Fox & Anchor near Charterhouse Sq.

That one in Borough Market

I bet Bentines will be along shortly to suggest the London Tavern on London Street, ha-ha! 🤣😂😆

The Old White Bear. Marginally closer to Central London than the Holly Bush, but further away from Hampstead station.

If you want a pub fire have a look for one whose planning permission to knock down and turn it into flats was refused.
