Once at Katenjammer and once a small amount of Caron's helping from the 1907 Restaurant at Brooklands Hotel where we were this weekend.

I see what you mean that it's something like pasta with cheese hence macaroni and cheese is an obvious comparison but... well, it's definitely more like macaroni and whatever-macaroni-and-cheese cheese is than it is like (say) orecchiette and parmesan. It's got a comforting feel to it rather than a "this is posh nosh" feel to it.
