I work in the building and am glad to have Cafe 300 downstairs for when I haven't brought lunch and am too busy to eat out. The place is clean, efficiently run, and reasonably priced. Although there are several options, I invariably end up getting the meat and veggies (found between the sandwich stand and the pizza).
Today, I had melt-in-your-mouth tender turkey, which the chef double-checked was gluten-free. For sides, I got green beans and broccoli/cauliflower. The other side options were mashed potatoes and rice, both of which looked good, but I prefer green food to white.
