There are three bed and breakfasts (I stayed at the Bay View Inn, which was lovely), a couple of ice cream/sandwich places, and a few gift shops.
The three restaurants which are open for dinner (one of which has a last seating at 5pm) sell mostly an array of crab-based fare, including crab cakes, soft-shell crab sandwiches, and crab bisques.
The island is comprised of about a thousand acres, only about a hundred of which are actually inhabited (the rest being marsh).
About 500 people live on Tangier, and since no cars are allowed bikes and golf carts are the main forms of transportation.
The best part of Tangier Island is the crabs and observing the economy and culture that has been built up around them.
