I walked to Boston Pizza from the Stratosphere on a recent trip. The employees were nice and the food came out fast. I ordered a cheese pizza, and my friend ordered a double pepperoni. The crust was golden yet soft, the sauce was delicious, and the cheese -- and the amount of it -- was very generous. Considering the cheapest meal at my hotel was $15, the pizza and drink combo at $6.99 was a great value.
We visited during the day, and it's obvious the neighborhood is a little rough; we were approached by three panhandlers while walking. I'd order delivery next time, especially at night.
I didn't know at the time of visiting that they deliver to the hotel. If I stay there again I will definitely order from them.
