Just got back from dining at your Sahara Location in Las Vegas. I was with my daughter and her family and placed my own order. The food was OK with the exception of the soda! I ordered a glass of Coca Cola which was watered down. There was no carbonization in the soda. I told the waitress who spoke or understood little English. Told her the soda was flat, she said I don't understand and just walked away. Another server was requested to bring a different drink and that was also flat. The owner/manager came out and told us since all out drinks were missing the carbonization that Coca Cola services and maintains this machine every week! On Monday, I will be in contact with Coca Cola here in Las Vegas regarding this issue. Anyway, when the owner/manager came out with a large bottle of soda for my daughter and family they were drinking sprite. I am not a Sprite fan and he nothing else to offer. I told him I wanted a refund for the drink since I did not consume it. He walked away and never came back. As were finishing dinner I asked about my refund of $2.25 again the owner/manager came over now he was pretty mad at me and told us to never come back. I guess where it is these people come from as it not from the USA to never come back to his place again. I guess where he came from it is ok it rip people by serving watered down drinks. On the way out I thanked him for service and told to look forward to reading my review on Yelp! His last comment was "What is Yelp"
