Areas with high concentrations of restaurants include the following:
Beltline Road: through Addison and North Dallas, just north of I-635, has perhaps the most restaurants per-capita in the U.S. If there is a type of food you like then you can probably find it there.
Greenville Avenue: running north to south in East Dallas, has many restaurants along its length, particularly in Lower Greenville.
McKinney Street: south of Uptown, a wide variety of quality establishments.
The West End: in the northwest part of Downtown has a good mix of original local restaurants and successful chain establishments.
Dallas has a good number of its own chain restaurants which have become quite successful in the area, offering unique local flavors.
Spring Creek Barbeque: Spring Creek Barbeque has 15 Texas style restaurants across the North Texas area. The menu is very simple. Beef, ham sausage, turkey, chicken, and ribs are available for entrees (you can have combinations also). Side items available are corn, beans, potato salad, cole slaw, and baked potatoes. In addition, fresh homemade bread rolls are served with each dish and more are delivered to your table during each meal. Even with large servings, the most expensive menu is only about $10 so all of the dishes are available at a reasonable price.
Cristina's: several DFW locations. Lunch specials are very reasonably priced. Service across all of the family owned and operated locations is blindingly fast no matter the location. The chips and salsa are arguably some of the freshest and best in the Metroplex. A unique signature menu item is the "Queso Flameado" where the server melts cheese by fire tableside and then wraps the gooey cheesey goodness in several freshly made tortillas.
Main Street in Downtown has seen major improvements over the last few months, with plenty of places to eat and to play. Highly Recommended. Don't forget to stop by the City Tavern for a longneck or two.
Taste of Addison: 4970 Addison Circle Drive. Includes food from over 50 of Addison's most popular restaurants, live music, arts and crafts show, children's entertainment, cooking demonstrations and more! Held annually in the Spring.
