Might depend on the branch. We went to the one in NYC and it was just ok.
Two things will put me off:
Impossible parking
And
Having to fight to get in a place.
I find it hard to believe that people in Idaho got their first In & Out and some waited 8 hours in a drive thru, I wouldn’t even wait an hour. Must be pretty boring life there!
Um. We had a KFC open up at our end of town — not the first or only KFC branch here, mind you — and the lines were absolutely ridic for the first day or so, which really fucked up traffic on a major road / intersection 
I never understood what compelled these idiots to line up for crap chicken. Did they think the place was going to disappear the next day? 
In n Out is just something new for the community.
People waited overnight here in Canada when Krispy Kreme first arrived, in 2003. I remember friends driving from Toronto to Niagara Falls and back, just for a Krispy Kreme run.
Some Ontarians would drive 60-100 miles to buy Krispy Kreme donuts. They were a big enough deal that the donuts were showing up at baby showers, bridal showers, and wedding reception sweet tables, placed next to the homemade baklava and tiramisu.
Then, a few years later, people got used to them, and eventually many of the locations closed.
The Cheesecake Factory in Toronto had people waiting with pagers for 3 or 4 hours when it first opened. I’m guessing it’s down to the standard wait time of a busy chain at a busy mall by now.
Shake Shack and Chick Fil A were a pretty big deal when they recently opened in Canada. I still haven’t visited, either. Not interested in Chick Fil A, and I’ve had Shake Shack enough times in NYC. It’s not like we are lacking good burgers in Toronto.
