I've never been to Johnny's at night, but I have been here for lunch during the day. It's a pretty awesome place for a burger. I wasn't sure where it was ... basically its down a little alleyway, and if you walk too far you find yourself at the doorstep of a stripclub. Sounds seedy, but its not. Its right off the main drag where Johnny's Downtown and Crop are.
Johnny's is definitely a hole in the wall dive bar - feels like you are in some restaurant's back room (which you probably are), but the lunch crowd was pretty much all young professionals pigging out on burgers and fries and onion rings. Which were delicious, by the way. It felt like a cozy little place, dark and tucked away, but friendly and not stuffy at all. I am definitely a fan, and will definitely be going back any time I'm craving a good fresh juicy burger for lunch.
