The Coffee Mill is the last living cell in North Baltimore's Belvedere Market. (Someone had to be last, right?) The Mill, operated by great people, Tom and Rosemary Thompson, is the only business left in what was, 10 years ago, a bustling new city market full of merchants and middle-class and upscale customers. Casa di Pasta closed a couple of weeks ago. If you walk into the market now, there's nothing but open space, the Coffee Mill and the aroma of the Thompsons' daily brew. The picture is not completely bleak, however. Within the next month, the Thompsons will move to a space up the sidewalk next to Greg's Bagels and Tech Lab, which has done so well in Belvedere Square, I'm told, it needed more room. It's a damn shame what happened to the market, made possible in 1986 with a grant from the city to developer Jim Ward. Still, the search goes on for a big nationally known tenant to fill the market space and keep people moving through the area and supporting the smaller businesses there. We hope someone signs on soon.
