Mexican Coffee - On the Border

Janae and I wnt to On The Border with Drake and Eleesha to enjoy some margaritas and mexican food.  Janae again had to remind me about the Mexican Coffee.  In my usual manner I grilled the waitress about it,  and she was only vaguely familiar with it,  she wanted to know if I knew how to make it,  but I told her I only want one if they have a way of making one,  I dont want them to make something I could make I want to see their specialty and try that.  She said okay and went off and another waitress / hostess that was sort of hovering / passing by a couple minutes later came by and asked "That Mexican Coffee is with Tequila and Kalua,  right?"  I said "yes,  but go ahead and make it the way you know it should be made".  I did not have a lot of confidence that it would be good and the waitress assured me it would not be on fire.
It came out and was certainly better than the one at Goodwood,  It seemed to have a stronger Tequila / Kalua flavor.  Also it had the benefit of following a strong Margarita, off the rocks (an invention of mine for the night where I asked for a margarita on the rocks,  with no ice,  which is basically like mixing Mrs Ts warm margarita mix with warm tequila,  not good,  but the drink was larger since it was not cut with ice,  so ANY drink was probably better).

Anyway,  On The Border,  you did okay but your questions and uncertainty on the Mexican Coffee help me understand that I have not found a great Mexican Coffee,  most certainly not the best.
