I hate those places squoosh
I went to St John twice years ago. Never again, and I like all kinds of offal.
The first time I ordered pig chitterlings, which is deep fried intestine. My choice, but it was absolutely disgusting. Greasy and cold, chewy rather than crispy. I think it might have been all right if it was hot, but it wasn't. I didn't complain, but I should have at the outrageous price for something that was badly cooked and would have been the sweepings of the abbatoir floor.
The other thing was a veal shank which came with a dinky spoon for the bone marrow. I ate the meat but left the marrow because I don't like it, and also, at that point as Zing says, it wasn't hot any more.
The waiter mocked me for leaving it. We did tip him because we're nice, but we never went back.
It was also freezing and white - like eating in a dentist surgery with the aircon turned up. I think that was because it was so long ago it was before the indoor smoking ban and because of the 'hearty' nature of the food it attracted cigar smokers.
It baffles me why this fucking place is still open.
