What a great place and very grand! What I love most about it is the fantastic sky ceiling and art work! This place is humongous and it'll literally take quite sometime to learn your way around. All I can say is follow the signs! If you can get used to which direction the Palazzo or the Venetian is, that will help you as a guide.
The stores at the shops are high end to mid range but you can find great sales. There is also a lot of easily found restaurants but you will need to follow the signs to the food court. From what I remembered; Subway, Panda Express took us sometime to find. I was recommended to eat at Table 10 (still have yet to try). We enjoyed ourselves here as a meeting point and attended a few restaurants.
My family enjoyed their shopping at Victoria Secrets and picked up some souvenirs along the way. Just a great place to eat and get some shopping done. It's just a huge place and will take some time to get used to.
