Baby friendly place in the city?

[Frances2015]

I have a meeting in London (near Liverpool Street station) next week. My husband will travel with me to look after our 8 month old baby. Can anyone recommend a baby friendly place - cafe or play area - where the two could hang out while I'm at my meeting?

Spitalfields is nice, plenty of cafes or if it's a nice day a bit of green to sit on. Theres a Leon, pret, gourmet burger, giraffe etc. Chain cafes but very child friendly.
