During my last day in Vegas I was pretty tired of shelling out $25-30 per meal for something mediocre so I thought of walking across my hotel to Fashion Show Mall to find the Nordstrom's Cafe. The prices are the same as your home Nordstrom's, and the choices are great! You can get a large sandwich to share for $8.50 or one of their hearty soups for $4/bowl, $3/cup.
If you want something quick and easy like a sandwich without the Vegas pricetag, come here!
