I am lucky enough to have been able to try Carls Jr and they are pretty good. On our little trip this summer to Carson City, to see my granddaughter, I got to eat at Carls Jr in Bishop Ca, Carson City Nv, and Flagstaff Az, the Jalapeno Burger was very good and the jalapenos were crisp not mushy like some places. My only complaint is they put mayo on hamburgers, bleeck,.. easy enough though to order it without mayo and order extra mustard. by the end of the two weeks my wife was tired of eating at Carls, I had a lot of fun pointing out all the Carls Jr to her during the trip, she appreciated it
As far as In-And-Out goes, they're alright. They just have a very simple menu, although I hear there supposed to be a super secret menu you can see if you know where to find it

Theres an In-Out across the street from our offices in Pleasanton Ca, I ate lunch there one day, and I would eat it again,.... if there wasnt a Carl's Jr around;)
