I like to have healthy lunch options near work. I've found myself going to Le Petit Croissant somewhat often. I'll start thinking about where I should go for lunch, picture yet another mediocre-but-nutritionally-acceptable visit to Panera, and then remind myself that there's a real, not-Panera bakery even closer to my office than Panera is.
It *mostly* satisfies the healthy part. Their sandwiches and salads are solid, and I've now brought 3 different coworkers here who have all been happy with their food.
The only problem with the whole "I'm going to have a healthy lunch" idea is right next to the register there's a bakery case of delicious morning buns and cinnamon rolls (among other things) staring me right in the face while I tell myself, "no, you are not allowed to bring one of those back to the office after lunch."
Most of the time, I manage to resist the temptation, until I don't.
UPDATE, May 2017: I hadn't been here in a few months because I changed jobs and don't work in the neighborhood anymore. Hit them up for brunch today and turns out they have a much larger breakfast menu with a bunch of Mexican items. Very good. I posted pics of the new breakfast menu and the huevos rancheros and veggie omelet we got today.
