I really enjoyed the food I had when on a detox in a mental hospital over 10 years ago. They never tried anything fancy (or with posh names) but it was very good honest cooking. Four meals a day with cooked lunch and tea both with one vegetarian option on offer. The system they used where food from the main kitchen was taken down to some of the wards including mine by van and then plugged the units containingg the food into the ward kitchen/serving area worked well too. I doubt the hospital does food the same way now though.
