<<Disclaimer: Verify this information before applying it to your situation.>> Thank you to all who helped with dining suggestions in Las Vegas. We always ate on off times so we could ask a lot of questions. I had the best luck at the Rio World Buffet. The manager was very knowledgeable and sat with me and went over every food item that I could have. She even had the chef broil me the steak of my choice. The chef at Treasure Island buffet came out and went over a map of the buffet telling me what was safe. He suggested that I just ask when I go through to have a fish filet cooked for me because the fish on the buffet was sitting in a white sauce. The Aladdin buffet and the Cheesecake Factory at Caesar's (terrific portabella mushroom) were also extremely helpful. I would stay away from Binion's Horseshoe cafe. They said there was no MSG in the steak but I reacted shortly after we ate. Jill in Illinois
