From Yeshivat Moreshet Yerushalayim online:
“Three meals a day will be provided by the Yeshiva and served in the cafeteria. Students will also be permitted to visit the many local eateries if they desire. Also, there are many mini markets where students can purchase snacks and drinks to stock their rooms.”
Very reasonable. They can keep snacks and drinks in their rooms. They are also free to eat out if they want and have the money to do so. Plus they have meals provided.
