I think you're thinking of La Cambaleau (sp?) in the 800 block of Calvert Street. It's been open a month or two. Nice selection of good cheeses and meats. However, the prepared food (sandwiches, quiches, etc.) isn't that greatat least not worth the walk, to me. Maybe it needs to be around for awhile, for the smell to permeate the place, then the food will taste better. It's too "clean" now.
yes, it's Combalou on Calvert. There is another post back in November if you care to look for it.
I personally enjoyed my one lunch there. Both the warm prosciutto sandwich and three cheese quiche were quite tasty. The quirky decor is fun (faux Jersey cowhide covered booths). And if I recall correctly, they are BYO with a $5 corkage charge. Which is considerably less than the typical restaurant wine markup anyway.
