Chicken & Waffles

What's a ballpark calorie estimate for one of those wide, thin waffles you would find at Roscoe's, Gladys Knight's, or any other chicken and waffles joint? The database calorie counts for waffles seem to vary drastically depending on where it's from, the style (Belgian, Liege), etc., but I have noticed that waffles from restaurants who specialize in the dish are usually pretty identical.
