First and last impressions count, and both were good at our weekend brunch at beautifully restored Brennan’s. Our starters of shrimp-and-okra gumbo and perfectly fried green tomatoes topped with lush crabmeat were both winners. Things got wobbly with an entrée of shrimp and grits, a case of overgrilled shrimp and too many ingredients vying for attention. Still, a great finale of precisely tart lemon meringue pie garnished with blueberry coulis and fresh blueberries left a sweet taste in our mouths.
