If not for the food, this is a great place to go for 24 hour service and free wifi for finishing up some last minute work. The waitstaff don't bother you and I didn't feel any obligation to buy food, it's great for students! Came on a Tuesday night and it seems like they have a place reserved for worker bees, noticed other patrons who were working only had a glass of (free) water or nothing at all on their tables.
