We were just at the GF, and in addition to the usual pastries & fruit, they had yogurt (three flavors) with toppings, oatmeal with toppings, and a variety of sliced cold-cuts & cheeses.
When we stayed at BWI in November, they had hard-boiled eggs, oatmeal with toppings, and small cups of Greek yogurt with berries (plus assorted pastries).
