It was an awesome vibe and Rotorua was lucky Rotorua to have a small venue like it, he said.
"I think it's something special Rotorua has."
Williams said his show was about comedy itself, because he was a bit worried about comedy these days.
One of the reasons for this was the way comedy reinforced stereotypes and often just went with the status quo, he said.
He hoped his comedy would challenge, offend and, most importantly, make people laugh.
Williams said Wellington-based touring comic Rhian Wood-Hill was "a friend who has been developing a fan base in Rotorua, and is a very talented comedian".
"You get two comedians for the price of one - it's genius."
