If you are in need of an Asian food fix, Noodles is a good choice in the Bellagio. It's a bit hidden in the casino so you may want to ask for directions. The casual eatery has a large selection of dishes to choose from. I recommend picking something with noodles, hence the name. I had gotten the wonton noodles before, and it was pretty good after adding some salt. I also recommend the Thai iced tea.
Unfortunately, today I ordered the Hainanese chicken with bones in, and this was the worst I have had. The chicken tasted a bit funky and was very salty. The soup that came with the dish was salty too, but it tasted ok after eating the chicken. That's how salty the chicken was. It overpowered everything. The side sauces were nothing special just minced ginger, chili, and soy sauce. I had to ask for a sweet chili sauce to make the chicken more bearable. The fragrant rice that came with the chicken was the only good part of the dish. It costs around $22 too!
Overall, come here for the wide variety of Asian food and stick with noodles. The menu has traditional Mandarin too for those who like a Mandarin menu. This is also a good choice if you're dining alone since there's a row of individual seating on a low bar style area.
