Though Brandywine Flowers is known for its wedding arrangements, silks, tropical plants, balloon bouquets and gourmet baskets, guest critic Lyman Chen gives the 48-year-old establishment a plug for customer service. “Brandywine has always come through for me,” he says. “Whether it’s a thank-you arrangement for one of my clients or a Mother’s Day gift for my mom, the folks there do a fantastic job every time.”
