How fitting your name is………
There are Jews in Boston and many other OOT communities. That does not mean that there are sufficient numbers for a ‘decent’ kosher restaurant to be viable.
40 years ago I owned a kosher restaurant in a New England city that had 30,000 Jews. The politics of kashrut supervision were such that after a few years I sold the lease and equipment to a non-Jew for a treif restaurant. It was not possible to satisfy the kashrut requirements of each small group and make money. In a large city such as NY there are enough groups that hold by particular shitas for many restaurants to pick a group to serve and be profitable.
