Living in Canada, I have been forever without Five Guys and In-and-out.
The best burger place around is called Mr. Burger, but it's single restaurant deliciousness and not a chain, so other than that we only have the mega chains.
A Five Guys finally opened up near us. Ignoring the ridiculous price (my wife and I ate for $18 not including a drink), the food was quite good.
I would rate the burger a small step above mega chains, and the fries WAY above mega chains. The fry portions are ridiculous though - my wife and I didn't finish a shared regular fry.
