First time in the U.K.

Greetings all, so I'm heading to the other side of the world for a few days and I'll be between Oxford(where I'm staying) and London(where I plan on going to take in a bit of well, everything) specifically. I've seen a few posts with suggestions for cigar lounges that are "worth the money", which I'm always interested in, however, I'm never opposed to spending a little extra for an experience in a noteworthy place that's comes with a nice story, or a little less at a place that's not as well known but is always a great time. With that said, I'd love to any suggestions anyone might have with regard to cigar spots you've enjoyed in or around London/ Oxford.( feel free to include any interesting restaurants as well!).
