I've only had it at 50's Prime Time Cafe twice (but that was years ago; now that I'm over 50 even with working out I have to watch my calories, LOL).
It's good but too much IMHO for one, so each time I split it (and they always brought it out on separate plates). I asked for dark meat, as I despise fried chicken breasts. They split it and included sides for each, not sure if it was a half order of the sides, but it was plenty for each diner.
First time, I was alone with my kids (they were 5 and 7 at the time) and we ducked in to escape a sudden downpour. We sat at the Tune In Lounge attached to the restaurant, and the bar tender said they served the full menu at the bar. So, that's where we ate. Just a thought, if you don't have an ADR and find seats at the bar, you can eat there too.
