Going to work in London for 9 days in July, suggestions on what to do after work?!

I'm so excited to be staying in London for work soon and would love ideas please on how to make the most out of it for ideas or restaurant suggestions when I leave the office round 6/7pm each night?!

I'm lucky I've done a lot of the touristy stuff in the past a few times (tower of London, London eye, churchill's bunker, etc) but I haven't been in 5ish years and googling just brings up the classics.

Would be so grateful for recommendations for places that are open later, great restaurants and/or pubs, etc.

TIA!!
