It's hard to find a good Chinese place in Pittsburgh. Lin's is one of those places. They have a good variety of choices from Chinese to Thai/noodles to Sushi. I have yet to be disappointed by the place.
I also have yet to leave the place with the MSG sweats. The flavors are clean and while some of the sauces can be a bit sticky-sweet, it never is to the point where you don't know what you are eating or feel like you just had dessert instead of a meal.
My favorite thing on the menu has to be their Hot and Sour Soup. It is definitely one of the best you will find in the area. It is actually both spicy and sour with a hint of sesame in the background. Not over spiced and not overpowered by vinegar. It has a wonderfully full flavor and the bits of meat, tofu and mushrooms work wonderfully in it.
Their lunch special bento boxes are an awesome way to taste multiple main dishes on the cheap as you figure out what your favorites are.
Other great things are:
All of their sushi - very fresh and very tasty
Schezwan anything
Pan-fried wonton with garlic sauce (SOOOO GOOOOOOD!!)
Go. Order. Enjoy. You won't be sorry.
