Peter's No Frills is probably my favourite No Frills. Back in the day, it used to be a cheap and scummy Knob Hill Farms, now it's just cheap and cheerful.
What's most impressive about this No Frills is that it has the selection to compete with much more expensive supermarkets, like Loblaws or Sobeys. They have a butcher and fresh fish, and a fair amount of stuff that's rare in supermarkets, like mexican mole.
If you can't wait to get home to eat, there's a hotdog vendor by the entrance who seems to be there year-round. On the other hand, it might not be a bad idea to fill up before going in, to keep yourself from too many discount impulse buys.
