I second the Victoria, but if you leave through the back of the train station you have the Warwick, the Lamb and a couple of great pubs down on the river there too
That area can be a bit sketchy so not sure about decent pubs, but the bar upstairs at the Pilgrim hotel is really nice. About two minutes from the station.
. Reminds me of working there years ago and going online “fancyapint” to have it quite bluntly say “there are no good pubs in Paddington”. A bit harsh !
