Thanks for all of your ideas! In the end, my dad and I had one restaurant in common after doing our respective research: Man Chun Hong, which is at 5953 Buford Hwy in Doraville (less than 5 miles from Perimeter Center and a very easy ride). https://www.manchunhong.com
A week later, I’m STILL thinking about the food we had there, and I’m a bit of a snob about Szechuan, so that speaks volumes! There were 8 of us, including a few teenagers who generally prefer more Americanized Chinese food, and even they said it was some of the best Chinese they’ve had. We ordered:
-Western Lake Beef Soup
-Hot and Sour Soup
-Szechuan wontons w/red oil (note: not sure if there was a language barrier, but in every other place I’ve ordered these, they’re small wontons floating in chili oil. Here they were a tureen of soup–and DELICIOUS.)
-Steamed pork dumplings
-Sizzling Black Pepper Chicken
-Szechuan Shredded Lamb Meat w/Cumin
-Baby bok choy with garlic sauce
-String Beans with minced pork
-General Tso’s Chicken
-Pork fried rice
-Mixed seafood with noodles
The last 3 were for the teenagers. 
If there was a ‘disappointing’ dish, it was the sizzling chicken, which was SWEET. To the point that someone wondered aloud if the chef mistakenly grabbed the sugar instead of corn starch. Doubtful; more likely it was that after eating so many other things with a high level of spice that it tasted sweeter than it was. So really not bad, but OMG THE LAMB. This is one of my go-to dishes and it was spectacular. Chock full of cilantro STEMS, which not only added flavor, but also texture and a visual bright green with the dark lamb. Just typing about it I’m wishing for more…
Everything else (including the steamed dumplings) was done beautifully. The Western Lake soup is known to me as West Lake Beef Chowder and it’s something I was introduced to by some HOs here in NJ. It’s wonderful, and while the rendition in GA was slightly different from the one I get locally (much less white pepper), it is still highly recommended.
Thanks again for your help! Do report if you get there!
Btw, we also took a ride to Your DeKalb Farmers Market, which was about 10 miles away. Unreal selection of everything and a fun food excursion if you have time! It was just a bit of torture to know I couldn’t shop and then go home and cook…
