Sprinkles is pretty much what started the cupcake craze and its about time we got one here in Vegas.
I've been to a couple of the California locations so I knew what to expect. However, if its your first time visiting Sprinkles, I'd advise you to manage your expectations. The cupcakes are not cheap, about $4 for one and slightly cheaper if you buy a dozen. While that might seem overpriced, the cupcakes here are of course much better than what you would pick up at the local supermarket.
When I visited this location, there was a line out the door for both the cupcake and ice cream shop. Though there were probably 20 people in front of us, the line moved pretty quickly, about 20 minutes til we were inside. They have a rotating menu of whats offered each day but they of course have a couple staples available every day.
The cupcake ATM right next to is helps save some time if you know what you want.
The standard most people get is the red velvet, I find the frosting to be a little too sweet for my tastes. Avoid the rock hard sugar candy on the top, its just there for decoration. The wooden utensils are a nice touch and the people working are top notch. Be adventurous and try a couple different flavors to see what ya like the most.
