I've eaten here twice, and my wife and her extended family more times than that, and in every case the food and service have been top notch. Everything is well prepared and presented, and many dishes have a local and creative flair to them. On Friday and Saturday evenings you can expect a wait for a table if you're not there before 5:30PM or so; in a market where restaurants that aren't cutting it do indeed go out of business, this is your surest sign that the Half Shell is doing it right.
Today I took my wife here for a birthday Sunday brunch; we had the Fried Green Tomatoes and Crab Cakes appetizer, Gumbo, and for entrees we had Seafood Pasta and brunch Eggs Benedict. 5 stars says it all.
