Hi, all. I'll be leaving this Sunday for Las Vegas, so excited! Does anyone know if there is a reputable grocery delivery service on the strip? I have multiple severe food allergies. Usually, I bring dry foods (such as cereal, bagels, crackers, etc.) from home, but don't want to waste luggage space. The hotel gift shops don't usually have things that are safe for me to eat. I've already made several dining reservations and had contact with the chefs to advise them of my allergies. The groceries will be for breakfast and snacks. Thanks in advance for any useful input.
