You can't drive through, and they won't serve it to you in a cardboard box, but for flavor and crispness, Ed Lowe's restaurant, which has been on the Dallas scene for 32 years, is head and shoulders above all others. All day Sunday (11 a.m. to 9:30 p.m.) and on Monday and Tuesday nights, the $10.50 fried chicken plate is on the menu. You can get two large pieces of white, dark or mixed. And there are fresh vegetables, salad, soup or fruit. And, hey, you can ask for seconds with no additional charge. Their secret? It's the marinade the chicken is soaked in for 12 hours. "Can't tell you what's in it," says Lowe, "but our cook got the recipe from his mother."
