Hi grantspain,
thank you for the pointers

Most likely I will not be able to attend EAG and suzo.sega are a bit far from central London, Hyde Park area,
but I've added a visit to the namco station and goodge street arcade to my agenda

Electrocoin seems to be operating and to be an interesting place to visit, but again it's far from central London and unfortunately I'm in a somewhat tight schedule...
I've been to Mine Head, a costal resort, for the nightmare before Christmas music festival three years ago, and they had a few new gen coin op machines but it lacked an old school retro lounge.
Honestly when it comes to arcade game preferences I'm 100% retro, give and take.
Here in Portugal, the "arcade golden age" is far far gone and it will be great to re-visit a proper arcade and get some of that good old thrill back.
