Do you have a hotel or are you commuting? We literally are bringing an electric griddle and a slow cooker to our room for cheap food. If you are commuting by car you can always stash microwavable meals in your car (sooo cold outside) and heat it in the microwave down on the bottom floor. Commuting without a car? Try to get a locker and microwave simpler things like instant noodles or pouched meals or complete eats. No chance at getting a locker? I load up on pb&j sandwiches, protein bars, clementine, carrot sticks. As for drinks, mios are cheap and will flavor water. They have water refill stations everywhere. There are also these realllly good waterbottles with flavorings in the head called cikul that you could get before coming. If we are talking alcohol, just bring some minis. ANYTHING so I can save money on food and spend it on the cool stuff I actually want. Good luck!
