After two years of restorations at the costs of hundreds of thousands of dollars, the Attendant Cafe is one of a number of urinal-turned-cafe popping up around London.
Attendant manager Jacinta Price said the owners wanted to keep as many of the toilet's original features as possible.
"It closed as a public toilet in the 1950s, so it had been a vacant building up until 2013 pretty much, so it was a mess in here," she said.
"I've seen the photos on the wall and it looked pretty bad, so there was a lot of clean up involved, which was pretty brave of them to take that on."
Customers said the concept is thought provoking.

"Well it's a really creative use of space. It's really interesting," customer James Hankins said.
"You look around, you've got the urinals over there, I'm not quite sure, this feels like it might've been the stalls. But yeah, it's just really quite interesting."
Customer Stephanie Aue said it does take some imagination to understand the appeal.
"I don't know, you think about it maybe how it must have looked 100 years ago and how many people have come in and out; and we were just talking about how many stories must have happened here.
"It kind of lets your fantasy run a little bit."
