Been in hospital in two big cities and worked in one -
First one - food pretty awful, but because I worked there knew they had a secret menu - so could ask for baked potato, chips, sandwiches, fried fish, fried chicken etc . Bit more palatable than endless plates of fish/chicken in cheese sauce/gravy .... and milky puddings (sago, semolina, custard, angel delight, blamange, cold tinned fruit with hot custard, ‘ice cream’ that was like soup) . I do remember that we had to date stamp a lot of things - pre packed cheesecakes lasted three years . God knows what was in them ...
At Christmas and on Sundays they did sometimes do nicer stuff - Christmas time one year they offered everyone banoffee pie, it was actually a proper slice someone had made fresh . They also did eg slices of Christmas cake, and for tea on Christmas used to offer like a ‘picnic’ tea sort of thing with pork pie, sausage rolls, mini sandwiches etc .
Even little things like actually getting access to sauce and jam used to be a faff though - lost count of the number of times we had to explain we didn’t have much of either . You’d just get an assorted box of both which could be 50 salad cream and two tomato sauce, or 45 black currant jam and two marmalade ...
Second hospital - horrendous . In for thirty six hours - they gave me a single roll with jam, no water, no tea etc - told me I missed lunch because I was having a scan, missed dinner because I was asleep . Patient’s mother in next bed went to WHSmith for me and got me a bag of stuff, was so bloody hungry and thirsty !
