This is one of my favorite malls in Vegas. There are a bunch of shops as well as restaurants and a food court (in case you don't want to pay some of the outrageous Vegas prices). This mall is in walking distance from the strip as you take the bridge from Treasure Island to get to the mall. In the summer time it gets super hot so you don't want to be outside as much. You can also be normal and drive to the mall.
Some of the stores here are the huge Macy's store, ABC store (like in Hawaii with your assortment of Vegas tourist stuff and wide selection of alcohol), the Marc Ecko Cut & Sew store and many other stores. I usually buy a lot of clothes from the Marc Ecko Cut & Sew store. This the the Ecko brand but the not gangster Ecko Unlimited brand. Make sure when you go to Macy's you mention you're from CA to get the CA discount. Saves you some money there.
There are upscale stores such as the LV store. They also have fashion shows showcasing different types of clothes. I went last time and they were modeling swimsuits. The stage is in front of the Marc Ecko store and it rises from the ground. The Apple Store is always packed here too. I was super close to buying an iPad but I told myself I was going to gamble money to win big. I bet money on sports betting in hopes of getting a huge payday but instead three of my picks decided to tank it!
They have a Paul Frank store too so if you're into Paul Frank, go here. The workers here are generally nice unless you're acting really stupid.
Remember that you're in a mall and you're going to spend money. If you don't like the prices here, don't buy anything!
