London is a bit of a push for me now as I moved up to Sunny Norfolk, but would be interested if there is a more local one👍🏻I think events are purposely secretive, so as not to attract the attention of uninvited guests. That said, I agree the website could be a little more informative.
I'm on the mailing lists for Red Bar London and Red Bar South East. Each one runs semi-regular events and once on the mailing list you'll be notified of dates, approximate locations and a teaser of the event. You can then reply to secure your place, and once secured you will get the full, detailed event information.
I'm not sure how I got on the lists in the first place though - possibly through their respective Instagram pages.
Yes I heard your name dropped, and Mike seemed very impressed by your question 😉
