I was going to post this in response to the question about what's good in the market, but decided to pull it out as a separate thread.
Several people have recommended Matt's in the Market, but I'm going to go against the grain here... My one experience with Matt's left me wondering why everyone gives it so much praise. Here's an overview --
I ordered the catfish sandwich with a side of farro and pancetta soup. The soup had a decent flavor, but I had to do a lot of skimming to make it palatable. There was so much grease floating on top of the cup that it really grossed me out. Now, I'm not on a low-fat diet by any means and I love butter and oil and bring on the fat, but I don't want to see my food swimming in it. After I skimmed the cup, the soup tasted just fine without all the grease and I didn't have to look at it in every spoonful. Okay, so maybe that's just an issue of personal preference, but then again, isn't that what this is all about? I digress. Moving onto the catfish sandwich. The fillet was coated in a spicy cornmeal breading and pan-fried. Unfortunately, the fish was rather soft, like it was the last possible day they could serve the fish before throwing it out. The bread was cut so thick that I couldn't possibly eat it as a sandwich and had to attack it open-face style. There was some sort of thousand-island-looking sauce spread on the bread, but the catfish breading was so spicy that I couldn't even detect the sauce. I have nothing against spicy food, but why put something there that doesn't contribute to the flavor?
Maybe mine was just an unlucky experience, but I didn't find anything compelling to bring me back for another try.
