It varies by program. At the places I have been, the residents lounge foods range from a bowl of fruit to a closet full of chips, candy and oreos, to whatever tray was leftover from various departmental meetings earlier in the day. During interview season, the PD puts out a nice spread for applicants that residents hit like vultures. There are various sponsored breakfast meetings and grand rounds throughout the hospital that you can sneak into and grab food during each week, definitely not a daily thing, and definitely fewer than were the norm when drug reps were allowed to pay. Thanksgiving and Xmas, the hospitals generally put out food for the staff. Other than those examples, at most places, you are on your own. Plus bear in mind that months you are on at night, none of these spreads put out for meetings helps you much, so you are stuck grabbing Oreos at 2 am when you finally ave time to eat. One or two places I interviewed at gave residents meal vouchers as a perquisite, but those only help you if you have time to eat at a time when the cafeteria is open (not always the case), and the places that offered those perqs always seemed to be offering that because they lacked in some other aspect that was important to me.
