Saslove's is my favourite. I'm not from Ottawa (used to be), but when I go there Saslove's is always a stop when we're getting supplies for a cook up. It's in the market and they've got some great variety, including exotic meats.
I seriously wish we had a place like that in Toronto.
i heart saslove's as well, and go there most often as I live close by. However, when I make the trip south on Bank, I always make a trip into the Glebe Meat Market. Family owned and operated for decades, they will get anything you want. I am roasting a piglet for Thanksgiving this year, and I would only trust them with getting it for me.
