Never have in the house, but I make good use of it at the salad bar of our local Harvester. I say never when I mean rarely; Morrisons do a low-fat 'slaw which goes very well indeed with one of their super big fresh pizzas*, but its an uncommon treat these days alas.

* Is there a pizza thread too I wonder? Here in the UK we have a weird take on the pizza that falls somewhere between the nastiness of Pizza Hut and the relative sanity of Pizza Express. The Morrisons Pizza is very English, though I see ASDA are now pushing something they're calling calzone (try saying that in a Sean Connery 007 voice). For the best calzone, go to ASK. Wells is good, but York, I think, on the whole, is better.
