Enjoyment of Yak and Yeti will depend greatly on what your usual expectations of various Asian foods are. If you like going to your local family Chinese restaurant, then you will love it. Go and try something new and have fun, it's such a cool building. If you like that new thing that you've tried, find out where you can find it close to home and expand your palate even more.
If you're the kind of family who has a favorite Dim Sum place for Sunday brunch, a Szechuan place for Friday night, and another place where you get xiaolongbao for lunch... well, Yak and Yeti isn't bad, but you'll be longing for home. DH and I always eat there, and it's fine, but it makes us homesick and we immediately start talking about getting a hot bowl of pho as soon as we get home.
