A little difficult to find, we walked around, tried the door indicated and it was locked. We were about to walk away when we tried the door ten metres away and it opened with a sign pointing downstairs to the actual arcade.
It's actually a bar with good priced beers and lots (40ish) of older arcade machines, the ones 50 year olds (me!) remember well. Packman era. We changed a couple of notes at the bar when ordering drinks and could have stayed there for hours. You find an old favourite. My daughter played Ms Pacman for the first time in her life and was plaesed to get 5000 points, my wife had a go, even my son had a go...then I showed them the old magic and first time got about 32000 points. The secret always was to forget the little pills and only eat the magic big pills when the four baddies were chasing you, then catch them when they are blue. Once learned never forgotten :)
If you just want a beer, loads of sofa's to sit at and you will be with locals, not tourists. GREAT FUN, highly recommended. Initially discovered on "HONEST PRAGUE" and their youtube videos are well worth watching before you go to Prague.

Cool dingy underground bar with a pac mac game (amongst many others!). Make sure you take change for the games.

The place was easy find using google maps and it's pretty centrally located it's only like a 5 minute walk from the high street.

The drinks and good and the prices are reasonable. The machines are 10Kc and 20Kc for the pinball ones which is cheap.

If you're into your arcade games I'd recommend popping down but there isn't much of a variation of machines, I've been to similar places in the UK and one in Krakow and they all had a lot more availability.

The staff are friendly too which is a bonus, I'm glad I went it's a good place to kill an hour.
