20 odd years ago when I worked in London and lived in z2 but many of my friends all lived out and trained it in, a good way to do birthday drinks was to reserve an area in a boring bar in C London like a Slug and Lettuce.
I would order some chips for most people and pay for those and buy a couple of bottles and then everyone got their own drinks.
Bit mainstream and basic but it worked - so I did it for about 3/4 years in my 20s
I am now older and have done more "generous style" hosting where people come and we pay for it all.
I am in striking distance of london and there are lots of people who I hardly see any more and I may like to do something similar (and in a similar way just pay for a few, not all of everyone's own drinks)
Is this a feasible option to do now we are older? if so where that isn't super basic and naff?
How would you do this?
