U Choy

I tasted a wonderful veggie at a Malaysian restaurant- U Choy. DH took me to dinner Thursday night at Malaysian Kopitiam in DC ( http://www.malaysiakopitiam.com/). I was pleased with the choice of veggie dishes/dinners when I had met a friend there for lunch a few weeks ago. They made an awesome veggie curry noodle soup and a very interesting salad- Achar- that was sweet/hot and included pineapple. This time I wanted to try something different and I found the U Choy stirfry. There was a choice of oyster sauce or garlic sauce and I chose the garlic. This was soooo good that I had to stop myself from picking up the plate when I was done and licking it clean! U Choy tasted a bit like broccoli, baby bok choy, and even a bit like asparagus. I found a picture on the restaurants website (http://www.malaysiakopitiam.com/menu_vegetable.php) and a link that includes a photo and description- scroll all the way down to the end of the page.

Has anyone else heard of this or tasted it?
