What could be better than a Sunday morning, a Sunday paper, a steaming cup of coffee, and a smoked-fish platter? All of those things at Miller's Café and Deli (2849 Smith Ave., Pikesville,  602-2233), that's what. If breakfast rolls into lunch, what better than a pastrami on rye, a reuben, or a chef's salad? Dinnertime already? Relax with a glass of Mogen David and a nice brisket or roast chicken. A little something sweet for dessert, or maybe you'll take home some deli from the deli? Why not?
