If we talking Sunday:
Brunch is for Nu Blacks (mainly female) that enjoy breakfast food but want something nicer than IHOP/Dennys/Waffle House. Fancy cage free omelets with mimosas and gluten free waffles. These are not sports fans.
Then you got regular Blacks that are chilling, watching football on Sundays during the fall. Spring it might be hoops, gym or video games. Maybe grocery shopping.
Then you got Ol Skool Blacks. They ain't going to Sunday brunch because they're at church. They not eating until it's time to hit up Furrs, Luby's etc., for the post-church buffet. Either that or everyone going to Big Momma an 'em house for dinner.
