JitB seems to be widespread in Seattle area, and never had it. What distinguishes it, its menu, etc. from McDs/Burger King/etc.?
Well as I mentioned, price is definitely part of it. The burger combo I get (a huge double cheeseburger and fries/drink) runs like $8.50. A quarter pounder (which is actually less meat than the JitB burger) combo at McDonald's pushes to about $11 by me when you upgrade to the medium fries/drink.
Their meat seems fresh, but maybe not as fresh as say Five Guys, Habit, In-n-Out or even Wendy's (but they're in the $10.50-11 price range for similar meal).
Fries are always hot, not soggy. And you have the upgrade option of seasoned curly fries... which are good.
They have that super-customizable drink machine. So you can get like diet vanilla orange Coke or whatever.
Menu is full of other options... tacos, jalepeno poppers, etc... again, all reasonably priced.
And things get pretty "fun" too. They have a "late night munchies meal", which is $6 after 9pm. Weird sandwich combos like a "chicken tater melt", which is this awesome sandwich on a croissant... fried chicken patty, hash brown patty, bacon and this crazy good cheese sauce. Combo comes with 2 tacos and a mix of regular and curly fries. Again, $6. If you want it during normal hours its' $8... which is still a huge value for all that food. It's like 2,100 calories.
So yeah you can see I'm a fan. They messed up my tater melt sandwich a couple weeks ago (no bacon, burnt the croissant) but every other time they're spot on.
