I just moved to Charleston, and my father-in-law is coming today (oh joy). He loves just simple, grilled fish. Where would be a good, moderately-priced place to go? My searches have turned up a lot of great higher-end restaurants, as well as a lot of low-end restaurants that fry fish. But I'm having trouble finding mid-range restaurants that grill fresh fish. But I've only been here a week, so know just about nothing about anything.
