Just came back from 太湖 (Tai Lake). I have been to David's Mei Lai Wah, Ken's Seafood, Jade Harbor, but never had the pleasure to visit the famous Tai Lake Restaurant.
In short, a thumb up from me.
I got the a dish which I cannot find online now. It is the black pepper cod on iron skillet (pan). It is not perfect with a couple pieces undercooked, but overall, the dish was executed with the correct philosophy and approach. This is a good thing. I am very happy. The service was polite and good. Despite that I had never eaten there, I actually knew a couple waiter and waitress because they worked elsewhere before. We chatted a bit about life. A small world.
I also ordered out the salt baked chicken. I haven't eaten it yet, but looking and smelling it. It seems to be the salted water chicken (鹽水雞), not salt baked chicken (鹽焗雞). This is getting more and more common, which is unfortunately. For people who can read Chinese, here is a short article describing the difference between the two:
Also came back from Dim Sum Garden again. Ordered the soup dumplings (aka juicy buns) to eat and ordered 八寶飯 out. Same good quality of service and food as before. Very consistent.
My favorite is Ting Wong. Great bbq pork and roast pork. Make sure to get half lean/half fatty for the pork. They also have good beef and gai lan chow mein and ja leung (rice noodle crepe wrapped around fried dough).
If you are interested in Chinese bakeries, Zhong Gang Bakery has really good baked pineapple buns and steamed egg custard buns. They also have good egg custard tarts. Everything is cheap, too.
If you like bubble tea, there's Tea Talk. They've got the machine that shakes the bubble tea and makes it really frothy. That's the way it should be.
All 3 places are on 10th Street.
I haven't been there in a few months, but I think Red Kings is really solid. I usually go for their Sichuan when their Sichuan chef is cooking. Their other chef is Shanghainese (their xiaolongbao, or soup dumplings, are sometimes better than this board's favorite at Dim Sum Garden). While they do have a lot of seafood on their menu, their fried rice and noodles are good enough that my less-adventurous partner really enjoys them and I am satisfied. My partner also really likes their General Tso's for the sauce and crispness of the chicken.
For your teens, in addition to the Yangzhou fried rice and General Tso's, I'd recommend the beef with spicy green peppers, double cooked pork, dongbo pork, and possibly, the cumin beef. You didn't mention what you prefer to eat, but their American Chinese (most of the first half of their lunch special menu) is well-executed.
Sang Kee is very good and has a varied menu to please the less adventurous. The peking duck is excellent. One of my kids is fairly picky and loves it there. She loves the wonton noodle soup (very big bowl); the chow fun, the lo mein, and the orange chicken (basically chicken nuggets with sauce on the side).
My family also loves Rangoon, if you are up for something non-fried. My kids love just about anything fried on the appetizer menu, as well as the chicken satay and most of the noodle dishes.
We don't get to Chinatown very often, but here are some suggestions.
Lee How Fook, on N. 11th Street, is not as good as it once was, but you can still get those favorites and they are decent. They always had good fried rice. Currently, spring rolls have replaced egg rolls as the crispy/wrapper item.
Also on N. 11th St. are two good Vietnamese restaurants, Vietnam and Vietnam Palace. I would recommend Vietnam Palace for going with the kids - it's brighter. The spring rolls at these restaurants are small and crispy and I think the kids would enjoy them. We have had good experiences at both of these places; they are across the street from each other.
