Meeting space for four people

[Jagger]

Can anyone recommend a suitable private space for two adults, a teenager and one four year-old child to meet near Dulwich Plough? We will be meeting once a fortnight probably on Thursdays from 5.30pm to 6.30pm. My daughter's taking part in a Healthy Eating (HELP)trial run by Great Ormond Street and this involves counselling sessions once a fortnight for the next six months. HELP's budget is ?15 for the hour. Dulwich Library, Christchurch, upstairs at Soupdragon and Push studios options have all been explored. Any suggestions gratefully received.
