Yes we have school dinners for lots of reasons (my laziness - no way am I making 3x pack ups in the am!, need for quick tea in the evening often, think they're good value, social reasons) but above all because I think they are good food and lots of it.
We have sessions where parents can come in and I am always very impressed. Also menus sent home every term. Have you asked to see a menu or an example of the food eleusis? Our school always puts out a display of that day's lunch on open afternoons. But a fussy eater (onyl peas as a veg) might struggle I guess.
sample menu might be lasagne with broccoli and potatoes, or roast chicken and veg and potatoes, also a veggie option always salad bar (so maybe tomatoes, cucumber, rice salad, waldorf salad (!) - as much as they like), pudding is a hot pud or yogurt or home made biscuit or fruit. Water and juice and milk to drink.
DS1 is at juniors and they can have seconds and thirds too.
Yeah I'm with roisin re tea in the evening - sandwiches, salad and fruit, plus milk or water, that's all I (or most packed lunchers) have for lunch so it's fine for an evening meal if they have had school dinner.
Anyway there are several days where it's all there is time for before we dash out to swimming, Rainbows etc. We never buy crisps either, apart from for parties, so 3x a year. I never know what to buy lol.
(Roisin - DS2 in bed at 6.30pm? Impressed!)
