If you're at the Venetian and you need a quick and tasty meal, Noodle Asia is your best bet.
The Venetian/Palazzo is great for fine dining, but it doesn't have a lot of mid range dining options. Noodle Asia is great for filling your stomach and satisfying your culinary cravings without breaking the bank.
It has a very typical "in casino" atmosphere, just feet from the extended poker room. You are always reminded of the fact that you are dining in a casino. The food is good, albeit overpriced. We paid $8.50 for a dim sum dish that would normally be $4.00.
Whatever. You're in Vegas and you're on the strip and it's 11pm. I really like Noodle Asia, but in reality, I only eat there if I'm about to hit the Venetian poker room. The food is good, but overpriced. The location is great, but you are sure to hit a mixture of bachelorette parties and locals trying to get a decent bit to eat.
