Where to eat in central London ?

[Alakazam8]

Hi I’m going to London on 30th July. I want to find somewhere to eat one evening for a meal that’s not fast food.
Has to be central -Leicester Square or near Euston, not too expensive £40 ish and lots of fun for a 9 year old girl.
I’ve been told to avoid the rainforest cafe but coming from further north I don’t know what suitable alternatives there are.
Any suggestions

Bubblewrap is my go to whenever we have any kids over or I fancy treating DS at the end of the week. The garden in Leicester Sq is a short walk away and you can sit and eat there. Amorino is lovely but v overpriced IMHO. Afterwards , pop into the Lego store if you have time. It has some amazing structures.
