The Great Hall is one of the most commonly used halls in all of Hogwarts because this is where students and staff gather for their meals. It is a beautiful hall where the roof is enchanted to reflect the current weather outside. On special occasions, the Great Hall would be charmed and decorated to suit the occasion, from Halloween to Christmas. The food cooked by house elves are absolutely divine. Breakfast, brunch and lunch are generally served throughout the day with snacks included during the off times until 5 pm when it closes so house elves can prepare the evening meal. Dinner is served only between 6 pm and 8 pm. The Great Hall closes for the night at 9 pm sharp and serves desserts and beverages until it closes.
