When I was at Kingston a couple of months ago myself and a few mates ordered a pizza at one of the local taverns there, it was a relvatively new thing for them only having got the pizza oven a few months back. We had waited well over an hour when I finally decided to ask them how it was going. They responded by showing me the first of my pizzas being currently made -as in, the toppings were being put on it. There was a line of about ten uncooked pizzas ahead of it
It wasn't bad pizza, but some advance warning (considering we ordered it takeaway) would have been nice. Apparently the had received 40 orders that night, for a place with a pizza oven that can handle two pizzas at a time.
We ended up around the same as you, 100 minutes.
