This place is so good that for a while my friends and I would get hot dogs every single Friday for about two months straight. A few times the owner even gave me free soup or chili because I became such a regular customer. Well, that and he's just a nice guy. There isn't a single negative thing I can say about Doyle's Dogs; from the friendly staff to the gluten-free buns, everything about it is perfect.
Edit: I'm originally from the Chicagoland area and I must say, Doyle's makes a pretty mean Chicago-style hot dog. Honestly, it's the most authentic Chicago dog I've had outside of the city...and that's saying something.
