DS's school use Harrison.
DS has just asked to go back to school dinners after a term and a half of packed lunch. He enjoys them, there are 3 choices a day, a 3 week rolling menu, you can only opt in for a half term at a time, no odd days.
Don't know how much it costs - £40 for this half term, 25th Feb - 4th April minus 2 bank hol days.
They do seem responsive - complaints via the school council that a favourite - Jamaican lamb Pie - had become too spicy has resulted in a return to the old recipe!
They will tailor the menu to the preferences of the school, and deliver some things ready cooked and some prepared and ready to cook, I think.
Yesterday the choice was:
mexican lamb wrap
fish in batter with lemon
Baked potato with beans and cheese
Lemon sponge and custard or yog
Today the choice was
Chinese Chicken
Tuna Melt
Veg Curry
with rice or something else
Strawberry jelly with apricots or yog.
They always have salad, fresh fruit and yog as a pudding choice.
They don't use processed meat except sausages.
