Cedar Key is a wonderful destination. There's a little grocery store but you can get everything you need for a great weekend.  Recommend you pick up a steak or some fish and grill at your motel.

There's a good collection of restaurants with interesting fare - from the basic fried fish to the elegant Continental menus. Here's a list of restaurants in Cedar Key.

As far as "getting around" walk or bike, there's a neat little cemetery on the north end of the island that is really peaceful. Cedar Key is a lot like Key West, without the drunks and without the tourists!
