Rocky Mountain Chocolate Factory is everywhere. It's seriously at every single mall- even Desert Ridge. I think it's a good place to buy someone a gift, but as for just dropping by and getting chocolates or caramel apples for myself, it's not really my thing.
But if you have a chocolate lover to buy for, they really do have a huge assortment of everything cocoa. They have the standard boxed chocolates, truffles, hot chocolate, candied apples, chocolate apples, caramel apples...you name it, they have it.
They also have a creepy bear that is always sitting outside of their store. I've never been able to figure out why. Maybe it's to lure little children into the shop so their parents will have to buy them bags and bags of candy...
If you like sugar-free chocolate, they have a good selection of that too.
