Popeye's chicken can be awesome, sandwiches or breast strips.
Unsure about chicken nuggets.  You will have to try those.
About Buc-Cee's:
The Beaver Nuggets are okay, not bad, I would not go out of the way to buy any.
Their brisket sandwiches though are the bomb.  Really good,  I think they have two sizes.
Seems like a lot for a sandwich, but it is a very good sandwich.  Arrive with an empty stomach.
Their bathrooms are very, very clean and have lots of stalls.  They may have 100 fuel pumps outside too.
