Where to eat with 5 and 3 yr old near-ish Nat Hist Museum or Euston?

[BadHair]

I'm taking my 5 and 3 year olds to the Natural History Museum on Monday. We'll be having lunch there but need somewhere else to eat before we head home, preferably near either the museum or Euston. Does anyone know of anywhere child-friendly somewhere nearby either location where we can get fed and watered without taking out a second mortgage?

Giraffe nearby, food not the greatest ever but super fun for kids and very friendly staff

Depends how close to Euston you need to be. There is a Pizza Express very near by but, if you are happy to travel a bit, I'd recommend Coram's Fields. It's near Russell Square tube so just down the road from Euston. It is a park with adventure playground, fountain, sandpit etc and a cafe which serves pretty good (vegetarian) food, ice creams etc. We love it!

The blue cafe in the science museum, next door, is very good

Giraffe also good. Also good selection of restaurants nearby on Kensington high steet - pizza express, wok wok and the like

Ooh, thank you. Blue Cafe, Giraffe and Coram's Fields all sound great - had visions of resorting to McDonalds so am much happier.
