The southern part of the old Northern Refrigeration building now has signs indicating Potbelly is coming. That will put one in the block north of Costello's and about a block south of Jimmy Johns.
Some work seems to be going on in the Enisa's space, but that storefront isn't large enough for much of a restaurant. A bit farther south the old True Value hardware store space has been cleaned out and for lease signs put up.
I still think the G P Franklin's space is most likely although I have to wonder about 200 seats. The signs offer a bit under 4800 square feet. Dividing that by 200, you get less than 24 square feet (equal 4 by 6 feet) per seat for everything including kitchen and storage. Commercial spaces often have for sale or lease signs up even after construction has started, so I don't think the signs mean much. It is possible that not all lease details are nailed down, though. No sign of any cleanup or construction activity. Wife hopes they keep the ladies room, which she regarded as the best feature of G P Franklin.
We stopped in Cafe Descartes for a couple of decent decaf espressos, quite unlike the horrible scorched flavor at a well-known chain. They roast their own beans, which they also sell as whole beans. They have a cooler with gelati and ices. The lemon ice appeared to be freshly made: peaks in the tray and not fully hardened yet. We resisted the temptation, though. Some other time, maybe after some soup for lunch. They seem to have three soups daily.
