If all of the profs on campus hide out in a certain place, you know it has to be good. I always hear mixed reviews about this place from my friends, but I'm going to go ahead and give it a 4.
This is my new favorite lunch place on campus (for when you have time). The sandwiches may be $1-2 more but are killer compared to other on-campus options. The grilled sandwiches may be a little buttery on the crust for some, but it's perfect for me. Last time that I went I got the grilled turkey sandwich which comes with caramelized onions and cheese.
Dinner options include fondue and pretty good pizza. They also have some good bottles of wine on the list, I've ordered a bottle twice and been happy with what I got. You might have to talk to one of the chefs if you want wine opinions since our server didn't seem to know much.
Really good atmosphere and decor, it's casual/fancy enough for pretty much anything, and it's right next to Krannert if you need an after-show dinner.
