Does panda express add msg or sulfites?

Well, honey, Panda Express does use MSG in some of their dishes, so if you're sensitive to that stuff, you might wanna steer clear. As for sulfites, they don't specifically mention adding them, but I wouldn't be surprised if they sneak them in there somewhere. Just ask the staff if you're really concerned, but let's be real, it's fast food - you're not exactly dining at a five-star Michelin joint.
