Was just there a couple of days ago. They will make you Margaritas, charge you double the normal rate "because that is the way we do it"
But they don't tell you before they make them. You only see it on the bill.
One more amazing factor, you order a Margarita and they charge you for the mix they put in the drink separately. I thought when I ordered a Margarita, the mix was included, talked to the manager and he said
"sorry senor" you must pay. The food was ok but nothing to write home to Mother about.
