Jamestowners are not anxious to spoil the small town ambiance with big box stores and chain restaurants and most businesses are owned or run by locals. Except for gas stations, Jamestown does not host a single "chain" or non-local business. Don't expect to find a Wal-mart; every restaurant and property on the island is, if not owned directly by a local, probably run by one. Some things require a trip off island but there are many large chain stores within a short drive.
