One commenter—Beerdrunk in Ballard—hates it:

Sadly, the Market Arms blows. Way, way too loud (it's basically a big box with wood floors, walls, and ceiling, it seems to amplify everything). It's way too crowded. The beer list is small and boring, though they have at least one good rotating tap. The food was unmentionable. Some sort of artichoke pesto dip, with a solid block of mystery cheese over it. We were advised by the waitress to "stir in the cheese before it cools and turns into a brick." Alas, the warning came too late.

The Market Arms is the new pub brought to you by the same people as the George & Dragon. Read (more) all about it over here.
