I go here for lunch buffet all the time and for my department this is the default place we go to when we go get lunch. We all like it because there are veggie options, you can get a good assortment of things, and it is very fast.
The buffet is very small, but always changing. I don't like spicy things and I rarely have any trouble with the food. I can't vouch for the authenticity of the cuisine, but it certainly hits the spot when it's a cost day at Purdue and you want something warm to open your sinuses.
