Bonkaz, real name Taylor Harris, was convicted of groping a 13-year-old girl in 2010 and ordered to sign the sex offenders register.
He was also jailed for three years in 2011 after taking part in the brutal kidnapping and torture of a 22-year-old disabled man.
He has also visited shops in Waterloo where he finds "peng chips" which soak up the salt to his satisfaction.
She is best known for her Internet character Miranda Sings, posting videos of the character on You Tube and performing her one-woman comedy act on tour in theatres worldwide.
The video featuring Harris saw the online critic and Bonkaz travel to Thornton Heath, south London, where they ate together at Morley's fast food restaurant.
But furious fans have slammed him for "the worst episode yet" and urged him to get rid of Harris and "stick to the basics".
