What a great place! I can't believe I've been living in Summerlin for 3 years, and just started coming to Nittaya's...
The food here is not exactly authentic Thai, but the flavors and the dishes are incredible! The noodles are delicious, but come here for the appetizers/tapas! Tapas are good for sharing, and I've heard their potstickers and wings are delicious! I ordered the Secret Spinach Salad....which, despite the name, is not at all a healthy dose of spinach. It's crispy fried spinach with an awesome tangy light dressing that is just a tad bit spicy....it's incredible. I also ordered the Crab Meat Fried Rice, which was very tasty and had some good chunks of crabmeat :)
I will definitely be back to try some more dishes. Decor is dark & romantic. Service is solid. Only thing is they don't really like to make substitutions/changes to the menu (ie we asked to remove the fried egg from the bangkok fried rice, but the waitress said no).
