There is no comprehensive meal plan.
Vegetarian choices are widely available.
Most students reduce meal costs by preparing at least some of their own meals in the residence hall kitchens. The kitchen areas are social centres in the colleges, places for sharing cooking and eating, brewing cups of tea and coffee, and socialising with the other students on your corridor. You will need to provide your own cooking and eating utensils, which can be purchased inexpensively on campus or in town.
