I tend to find most every chain restaurant and fast food to be tolerable at best. You like what you like, none of it is quality, some people enjoy it more than you, that's normal. Any hype over some new item or expanding restaurant is bullshit, but there are a few that are irredeemable as a whole to me.
Raising Cane's is just plain trash. Most sandwich chains are serving cheap Gordon's Food Service flavorless shit and everyone hates on Subway, but everything I've ever had at Firehouse Subs has tasted like it was put together from days-old discount frozen ingredients.
