From what I can make out, VideOdyssey is open three evenings a week and is part of Toxteth TV, 37-45 Windsort Street, Liverpool. Their website isn't working but these pages have summaries:

So it seems that VideOdyssey is more of a way of indulging in and sharing a hobby with other enthusiasts, run on the back of a main business, rather than a business that needs to be viable in its own right.
From the photos on Google Images and here
https://harrisonstringfellow.co.uk/projects/toxteth-tv/ it seems to be a large building that is home to various community and performing arts groups etc, so probably plenty of room for this chap's video rentals and arcade gaming machines somewhere.
I hope he succeeds, and most of all enjoys what he's doing.
