I've been to Hadley's for dinner several times in the past six months.
I'm not really a BBQ connoisseur, but their ribs seem pretty good for what they are--tender and moist, with an appropriate amount of sauce. Their fried chicken (Fridays only, I believe) is quite tasty, however, the deep fried skin is not attached to the chicken very well--but I forgive them!
Service is good and in my experience Hadley's has always been a chill, quiet environment.
