In a northern city better known for its annual street fair than dining fare, Hannah's Off the Square is a pleasant surprise. The owners have transformed a small corner of a vintage city building into a small piece of Europe near Denton's courthouse square. The quiet atmosphere, brightly colored décor, accented with copper and set off by natural stone walls, is just part of the pleasure of dining in one of the few Denton restaurants that recommends reservations, because it's one of the few that's good enough to need them. Hannah's chefs do a masterful job of preparing gourmet fare unparalleled for many miles around. Entrée highlights are the sesame-seared tuna and steak au poivre.
