The Trader Joe's in State College is like any TJ's you might have gone to before.
There's a selection of fruits, veggies, and ready-made meals. They have boxes of soy and almond milk and other drinks. They're one of the only places that sells Ezekiel (sprouted) bread, which I'm very grateful for.
If you take your time looking, you can find vegan cookies, candies, and chocolates, although it's hard digging through everything to find what you want. I did notice recently that TJ's carries a brand of soy ice cream sandwiches!
Overall, it's like a normal TJs. You'll definitely be able to find some snacks to eat or shop around for ingredients for entrees.
