I work in the building and this is my come-to when I'm working a late shift and the cafe has already closed. The large house salad is the best deal, you get to pack the container full of any of the selections from the salad bar.
My personal favourites are the tuna pasta salad and the broccoli florets (they toss it in some sort of dressing that makes it irresistibly delicious).
You can see into the kitchen and whenever you're ordering a hot dish (eg. protein salad, hot chicken sandwhich), they make it in front of you and always error on the side of being generous; I'm often amazed by their stacking skill.
