Gatsby's Bar was situated on the end of the Berkeley Hotel in Marine parade, now the Travel lodge. Originally a Cocktail lounge run by Geoffrey Cunningham.  It was apparently owned by the Varani family.

We're not sure what the previous history is but we think it may have been a bar called 'English's' in the late 70s. Possibly something to do with Pete

Pete English, or so we're led to believe. Colin (worthingpubs.com) recalls it from around 1985 and thinks it wasn't there long.

"In the Late eighties I turned Gatsby's Cocktail lounge (at the Berkley Hotel) into a live music Bar, great fun till noise abatement shut us down"

"The only picture I have from Gatsby's bar. This was "Switch" formally Stateside: if anyone has any pictures or video from there would love to see them. This was taken around 1986."
