For all that Dallas' dining scene does well, late-night food service is not a strong point. Beyond the usual pancake joints and freeway greasy spoons, there isn't much to pick from for eats after last call. When Zalat opened this spring, that changed. Five nights a week — Wednesday through Sunday — the New York- style pizza joint will serve you a pie as late as 4 a.m. The pizza, especially the creative and delicious Reuben, is way better than it should be for an after-midnight nosh. Worth staying out late for.
