Im late to this party and couldnt read everything but let me just say. The best biscuits and gravy goes too...
1) Hardee's
2) Bob Evans
3) Frisch's
Its probably all pig slop, but it does taste amazing! I thank god that there isnt a Hardee's within 25 miles of me, so at best i get to have it 3-4 times a year.
Mcdonalds has ok biscuits and gravy but its not top 10 list worthy.
