I've been going to Su-Chang's regularly for about 13 years. I live fairly close to the restaurant and my boss at the time, who lived in Andover, told me this was the only place she went to when she felt like Chinese. I figured it must be good so I went with my husband soon after and we were hooked.
The inside isn't super trendy (they haven't redecorated since I started going there) but for a Chinese restaurant, it's very nice. Even though this place is usually very busy, I don't think I've ever had to wait for a table. The servers are all very polite. I don't recall ever once having bad service, which is pretty good considering that English is usually not their first language, and we don't speak any Chinese. Most of them have a pretty heavy accent, but we never had anything lost in translation, you could say. The service is fairly quick, even when they're busy, and you never have to ask for a drink because they give you plenty of tea and water.
We go here about once a month on average so I've tried almost everything on the menu. Like most Chinese restaurants, their menu is absolutely huge. There were maybe one or two things I wasn't crazy about but the vast majority of the time the food is delicious. It's served family style, so we each pick out an entree we like, then we sample each other's food. It is a little pricey for Chinese (the bill usually totals about $60 for four of us) but they give you a boatload of food. Unless you have an absolutely massive appetite, you will leave this place with enough leftovers to last about a week. So, in my opinion, it is worth the extra money.
The only downside to the restaurant is the parking. The parking lot looks big, but it's cut out very odd and it's certainly not enough to accommodate all their customers. It was just me and my kids the last time we went and there were no spaces to be found. I didn't want to just park in front of other cars and block them in like some other people were doing, so I had to park on the cul-de-sac beside the restaurant. The neighborhood and Su-Chang's don't want people doing this, but I felt I had no choice, because there was absolutely no where else to park. I'm not sure if there's anything that can be done about this situation so I'm not going to dock them any stars. Just be forewarned: If it's on a busy night, you'll probably have a very hard time finding a place to park.
The last time I was there, I ordered the egg noodles with pork, chicken and veggies and it was fantastic, as always. They cook their vegetables al dente, instead of serving them nearly raw like most Chinese restaurants do. Since my family cooks veggies until they're limp rags, I prefer Su-Chang's veggies over other chinese restaurants. Probably the best thing on their menu is the crab rangoons. They always come out hot, with a crispy outside and creamy delicious inside. One serving is ten rangoons, and two servings is about 30-40 rangoons (yes the math is bad, but at least it's in my favor, so I don't care), so you probably don't need to order more than that unless you have a huge party. The seafood and tofu soup is the second best. It's usually chock full of chewy yummy calamari, tofu, and egg whites (I think). My favorite entree is the sesame beef. It's usually cooked to perfection, tender and drizzled with a yummy sweet and sour sauce.
I've been there for lunch a long time ago and I believe the menu is much shorter, so if you want variety, I'd go there for dinner. They also don't serve desert, but you get some pineapple chunks when you receive your bill. But like I said before, unless you have a massive appetite, you won't want desert anyway.
I definitely recommend this place, it's more than worth it. read more
