RECOMMENDED: Sorta of a local institution, expect periodic line-ups. It's cute, it's quick and it's good. Prices are reasonable and has beer for those in need. They also serve a very nice vegetarian burger as well.
Note: I'm not a big fan of the truffle fries, namely because truffle oil (meaning truffles in oil) is very $$$. Truffle oil is normally a chemical product using thioether (2,4-dithiapentane). So if you like chemicals.
