Step 2-CS is comprised of 12 standardized patient encounters as follows: 5 encounters, lunch break (30 minutes), 4 encounters, 2nd break (15 minutes), 3 encounters.
Our lunch (Chicago center) was salad and cold/cut deli sandwiches. The meats, cheeses, breads etc were laid-out separate and each examinee prepared his or her own meal. The food is arranged so examinees with dietary restrictions (i.e. all or certain types of meat) can prepare their meals with their guidelines in tact. As the proctor said, you can take as much food as you like, so long as you finish eating in the time allotted. They also provide bottled water and soft-drinks and some cookies/pastries for dessert. Enjoy!
Nice username, btw!!
