At first glance, this store looks like a tourist trap as it is in old town and they are selling Mexican trinkets. However, I can't say with absolute certainty, the prices seemed to be pretty decent. I bought a colorful straw sombrero for 5 dollars. I saw some other items that seemed to be priced right.
You can find all your Mexican things to make for a fantastic fiesta. Or you can find pieces to decorate your home with in this store -- from the colorful Dia de Muertos Masks to the plates and cups to the garden pieces.
I did not find the ladies in the store to be friendly at all. But the store is neat and you will be happy, I am sure, with the HUGE selection of trinkets.
