It's definitely cheaper to buy prepared foods from the Las Vegas WF deli - and beer - to take back to your hotel room. Skip overpriced Strip restaurants and crappy buffets - go to WF instead! It's one of the biggest WF stores I have visited.
The evening I visited - they were offering sample tastings of different types of RUM! I am not kidding - when do you see alcohol sampling in California WF stores? Try - NEVER!
The vegan mock chicken curry salad was delicious, as was their a kale salad. The Deli team member who helped me was super - she not only took the time to take my order and shepherd me to another item I was asking about, but connected with the other folks waiting to let them know she would be right back. The cashier was super friendly and gave me a complimentary bag of ice to take along with my beer saying "You can't have warm beer!" and wouldn't hear of me bagging it up myself.
It was like an oasis of customer service, value and calm in the middle of the insanity that is Las Vegas. I swear I would have gone running back out into the desert to spend the night at Tecopa hot springs without beer or food to get away from the excessive lights & crowds of Vegas if it hadn't been for WF to nourish me that night.
