Doña Celia's Restaurant in Coacoyul

We're thinking of heading out on Sunday to Coacoyul for some of Doña Celia's pollo en mole.

We haven't been there in a couple of years. Can anyone confirm she's still open on Sundays only, from morning until around 2 pm? Don't want to take the combi, only to find she's closed....and we don't have a cellphone.
