If you are planning to eat at Casa Don Juan you better wear a snow suit. The hostess was going to seat us in a booth next to the front window, so I asked if we could sit somewhere warmer. What about that room in the back, I asked? She said that room is closing (Two hours before closing time?!?). We got seated right behind the reception desk, first table as you turn the corner where every time the front door opened we got a cold... COLD blast of air. It happened to be 31 degrees outside and we thought a warm bowl of Cocido in a warm cozy Mexican restaurant would be nice. BIG, I mean "BIG" mistake going to Don Juan in Summerlin. Where the hostess frowned when I asked to be seated in a warmer area. The waiter made a joke when asked why it was so cold in there. And looking around everyone left their jackets on while they ate, just like me?!? I kept asking if they could please turn the heat on and they said they would, but it never came on. Leaving, I told the person at the register, "Your food is very good, but too bad I'm never coming back." Telling her about the situation she apologized and agreed that it is too cold in the place. She is the only employee that didn't look at me as if I were crazy!?! In parking lot we asked a couple walking out what they thought and the wife said she had to drink six cups of coffee just to keep warm. Suggestion: Casa Don Juan owner, TURN UP THE HEAT!!! YOU ARE LOSING CUSTOMERS...Don't be so cheap! (Cold @Main Street too!)
