This place just never seems to be empty. Good for them, but leads to a very noisy atmosphere - if that's not your thing, this is not a good place for you.
That being said, they have a lot of traditional French cafe food - croque monsieur, croque madame, merguez sausage, and in colder weather, boudin. Tuna Nicoise salad, quiche. Most everything I've eaten here is pretty darn good, and the service is surprisingly attentive and polite.
Fun place to come with a few friends so you can make enough noise to drown everyone else out!
