Add Smashburger and Shake shack to that list. Never had shake shack tho, the only one I've been by is at grand central and the line is ridiculous
I've never done Shake Shack--the lines are ridiculous at every location and no food is that good. I love Smashburger's burgers but the fries aren't great to me.
While I maintain Chik-fil-A is overrated (it is) I just had it this weekend. It's good, but it's not the awe-inspiring experience people make it out to be.
I also tried a Chicken McGriddle this weekend (on the way to CFA). The patty is peppery and the McGriddles are obviously sweet. It was a pretty good combo.
