London recommendations with child

My wife and I are going to be in London with our 8 year old in tow. He is well-behaved, loves food, and did pretty well at Bouchon - no iPad needed per previous posts :).

I’m not sure I’ll make it to London again, so would love to go somewhere like CORE which sounds like they permissive of kids on the website as long as they participate, but I wasn’t sure if it would raise eyebrows still.

Generally was hoping for thoughts and any recommendations, especially around places that are frequently recommended on this sub.

Thanks!

Edit: Appreciate the responses so far - was hoping to also solicit other good alternatives (or not to belabor CORE, but also on their a la carte lunch). Thanks!
