Yes I have, pretty good place, el capisano is another that’s good. I have tried la hacienda too, but wasn’t too impressed. Senor Fiesta beats all around here IMHO. Senor Fiesta is across Dawson Forest Rd from the outlet mall.
We used to hit El Rio in Cumming pretty regular but the quality went way down hill,. Lately we have been going to Los Rios in Cumming and I understand that the owner used to work at El Rio. I dunno if it is actually good Mexican but it is good enough to suit us until we find better.
I am kicking myself for not just stopping at El Jinete but I coulda swore I had a fix on Senor Fiesta.
