Bar Under the Bridge - Southbank?

Presume that this a renamed Hop Locker #3?

I haven’t spoken to a former colleague for about 2 years we’re both obsessed with parmos so texting her next!

Was about to comment saying you’re wrong and it’s #2 that’s the winter popup, but then I realised being “under the bridge” means it’s in the location under Hungerford Bridge which is indeed #3.

I assume this is a temporary thing just for the holiday season?
