All 4 stars are based solely on their Orange Tofu. By far the best tofu I've ever had. It's a big enough order to eat off of for 3 days (unless you're sharing) and I recommend ordering Chow Mein noodles to go along with it.
Other than that... Mr. Hunan ain't nothin' fancy. Panda Express has a waaaay better atmosphere and that's not saying much ;)
