I think in general I am flummoxed by the popularity of pretty must most large sit-down chain restaurants out there. They generally all suck. There is a tipping point at where you have too many restaurants and have to sacrifice quality for consistency, and then you fuck it all up. It's probably easier in fast casual places. I mean shake shack has it down pat and they have a number of locations. I like Jersey Mike's subs also, but have only been to three of their joints. Even though Shake Shack is better, I always had a good experience at an In n Out when I traveled to the west coast.
Once in a while I guess you may crave crap. I still have a soft spot in my heart every few months for a few soft taco supremes at Taco Bell. But around me to go to a sit down restaurant there are too many other options than to go to a TGIF, Olive Garden, Cheesecake Factory, Outback, Red Lobster or what have you. I haven't been to one of those in many many years, except once or twice when a date out in the burbs requested we meet at one of those places. For drinks, not dinner.
