That's fantastic 
I'd like it for grown ups too - I've had to spend quite a few spells in hospital and in one particular hospital the food is just awful - totally inedible.
Being in hospital is bad enough - especially for children - without having to contend with food you don't like.
That deli idea is the kind of food I often used to do for mine when they were little and for my nieces who were both fussy eaters - we called it bits and bobs
I think it's really good that they offer the same foods chopped in different ways - that's important for children who have problems eating.
