Time Out says
You won’t find this place on a map, so instead look for a glass door tacked with bits of paper assuring passers-by that there is nothing suspicious about what lies behind. Poke your head inside and you’ll discover that the interior is covered from floor to ceiling with notepad paper filled with doodles, initials and life advice scribbled by drunken backpackers and salarymen alike. Due to the highly flammable interior, this is a non-smoking bar.
The maximum capacity here has always been a point of speculation, as even when the place is packed and all stools are taken, new arrivals are ushered into the narrow space behind the bar with firm camaraderie. Always order the Suspicious Shot before you hop to the next bar; it comes with a dubious-looking purple sphere rolling at the bottom of the glass – don’t worry, it’s just a grape-flavoured ice lolly that makes a perfect chaser for even the strongest liquor.
