Good Asian/Ethnic near MOA?

Given all the road closures this weekend we're nixing On's with the relatives in favor of something closer to MOA where they'll be staying. They love Asian and ethnic food and there's at least one vegetarian in the bunch. We took them to Grand Szechuan last year, which they liked, but they want to try something new this time. I can't really think of anything else close to MOA that fits the Asian/Ethnic request. I think Masu just opened at MOA - is that correct and would it be a good choice? Any other thoughts? This is for dinner this Sunday night so I'm a little under the gun. Oh and there will be 2 kids and 5 adults - aside from the vegetarian I don't think we have too many limitations. Thx!
