The #1 best thing about Jarlings is the speedy, friendly service. Well, at least it was the one whole time I've been there. There were a ton of people there, but the line moved very quickly (which was good for everyone nearby--I had serious custard jones).
#2 best thing is, of course, the custard. I had a 'mini' butterscotch sundae, which was *plenty* if you just want a little something. Mini my foot, really. It's a large scoop of custard. SO worth it for the meager price tag of $2.55.
#3 best thing is all the fixings available.....like butter pecans or pecan pralines. Or both. I'm drooling just thinking about that. And I cannot *wait* to try a "Snickerette Snowstorm." Mmm....bad for me...
