I've been here a couple times and each time my family ask for no mushroom because of an allergy and every single time, they "forget" to not add mushroom. Even if I do speak to them in Chinese, requesting no mushroom because of an allergy... they still don't seem to understand or remember.
I had the unfortunate chance of going to their bathroom before I began eating to simply wash my hands and when I walked by the kitchen area, it smelled like dirty sewer or broken old pipes, my sister and I had to hold our breathes going in and out and I'm surprised the smell didn't make it out to the dining area.
The one thing I did like was the roasted duck here and sort of the snails, but they were a tad bit too spicy. The beef fried noodles tasted like they added way too much msg, and the beef tasted like it was sat out for couple days too many. Their sweet and sour fish was overly seasoned with the sauce that I could barely taste the fish at all. I'd rather go to HK Seafood Garden which is maybe two street lights away, at least there... I know I won't be smelling dirty pipes and consuming massive amounts of msg.
