I found this place last April when I took my first work trip to the greater Phoenix area. It is located just west of the main drag of art galleries in Old Town Scottsdale. For someone who prefers mild warmth to severe heat, the atmosphere was perfect in April. Having just been there in February, the temperature was a little chilly.
The restaurant has an indoor seating area, though I cannot imagine a scenario when I would try to sit there. There is also a full patio which is why you have no reason to go inside.
The patio (covered in the rain) has space heaters if it does get cold out. There is a beautiful fountain in the middle of the patio that mixes a fire and water show with ambiance.
The menu is a modified Mexican. Traditional Mexican meals and tastes presented in new ways. The food is very good and I am told their margaritas, though not the best in town, are very good as well.
