Where Can We Buy Premium Chocolate Bars in HoCo or Baltimore?

What stores around Howard County or Baltimore have the best selection of high end chocolate bars?

Frank Hecker, a mainstay on the HoCo Blogs scene, emailed me about finding speciality or unusual chocolates.  Like Frank, I'm a fan of really good chocolate bars.  They're small luxuries -- costing just a few dollars even if they're triple the cost of a Hershey's.  Frank writes:

I sometimes check out the list of top-rated chocolate bars reviewed at Seventy Perfect, and I've tried a couple of them, most notably the Michel Cluizel bars; they really are quite nice, definitely a cut above your typical "premium" bar (e.g., Ghirardelli, Green and Black's, etc.) and not much more expensive. I suspect the same is true for the other highly-rated bars I haven't had a chance to taste.

However the closest place I've found to get Michel Cluizel is Balducci's in Bethesda, and even they have a limited selection. I have no idea if anyone in Howard County carries these, but I'd really be interesting in knowing. High-end chocolate bars are a real bargain treat as far as I'm concerned, because a $5 or $6 bar will last me several days eating a piece or two at a time. It would be nice if some local business catered to my tastes, which I suspect might be shared
by others.

Can anyone suggest a good place to shop around Ellicott City or Baltimore?  Does Roots or any of the organic markets offer the good stuff?  As I remember, Produce Galore had shelves of chocolate, but they are regrettably a part of Columbia's history.  Is there a gift store or a coffee shop that filled the hap?
