I know this café is aimed at kids but really there isn’t much variety for adults.
Granny needs to eat too, the Questacon should realise that these kids are usually accompanied by an adult, who is completely over white bread sandwiches. This Snazzy Granny took her small charge, aged 7, with quite a discerning palate on him next door to the National Portrait Gallery which suited us both.
Granny had her tannin fix and grandson had a coke, which is not strictly allowed but what happens in the National Portrait Gallery stays there. Job done!
