Not a student, but my husband and I love coming here once a month.
Easily the best buffet in the city. $23 for non students ($13 for seniors and guest at the hotel) will get you consistently well made meals from all over the world, on a rotation all day, every day, there is something here for everyone - literally. Gluten free, vegan, vegetarian, kosher, halal and they can cater to even the most specific dietary restrictions.
Most of it is self serve, but there are parts like the pasta bar, burger and hot dog station, noodle, and rice stations where the staff will prepare your meals right in front of you. Staff are also always nearby to help.
The atmosphere is very relaxed, with mostly students just chatting, studying while they eat etc. Always plenty of seating available too.
