I haven't been to one in quite a while but my impression is that there is lots of added sugar in all the sauces they use, in addition to a lot of fried food.

Many of the sauces are sweet, and the recipes tend to incorporate every major food allergen you can think of. I still visit regularly because you can opt out one portion at a time: You can go half-and-half veggies and chow mein, broccoli beef, mushroom chicken and have something a bit plain, but far more balanced than most fast food. And while the service model is extremely scripted and doesn't accommodate larger orders gracefully, my average time from getting in line to finished service is faster than Mcdonald's and more consistent since the order is put together right in front of you.

food is scary and dangerous and it'll make you sick in subtle, imperceptible ways that'll eventually kill you. i just don't even bother with the stuff anymore tbh.
