I went to the Courier Cafe for a late dinner, and I left satisfied. Its more expensive than most restaurants in campustown, but the food is worth it. I ordered a burger, and it was very filling. All my friends were pleasantly surprised too. My vegetarian friends tell me that the vegetarian selection is good as well.
I'd recommend getting one of their hand dipped shakes. You may get sticker shock upon first seeing the price, but it is worth the money.
