London shops and restaurants

[thisisarequiem]

Hi,

Hoping to get some good recommendations for entertaining/different shops and restaurants for 2 kids age 11 and 9 at February half term.

Staying in Knightsbridge, they eat all foods and have some money to spend while we're there.

I've planned our activities and we've all been to London a few times.

Thanks 🙏🏼

M&M world and the Lego store in Leicester Square
Platform 9 and 3/4 at King’s Cross

Inamo
Bubblewrap waffles
My Old Dutch
EL&N
Hard Rock Cafe

Are they into Sci Go/Fantasy/Manga etc? There's the Forbidden Planet shop down Shaftsbury Avenue. Then 5 minutes walk away is Foyle's Bookshop which is heaven if they are bookish children.
My daughter likes a Japanese shop that sells cute kawaii stuff - it's near Covent Garden but I can't remember what it's called.
