Awesome, simply awesome!
Some of the best Hot & Sour Soup I've ever had....
I usually judge Chinese/Asian restaurants by they're Hot & Sour Soup since this is one of my favorite dishes, almost all Asian restaurants serve it, and there are many variations of it.
Although not the best I've had, Happy Wok has the most consistently good Hot & Sour Soup I've had from a take out restaurant.
(Just the right amount of sour, spicey but not too much so for other people, lots of black fungus, other mushrooms, and other solids.)
The only H&S Soup I've had better was at Lucy's, as well as my own that I make from time to time..
