Fort Worth Texas

I took my son on the bakery tour yesterday. We enjoyed it very much. Make sure you call ahead and schedule it though.

Cafe Ashton, The Chophouse, Del Frisco's, and Texas de Brazil are good for places to eat steak and upscale food. Ruth's Chris is coming soon. Avoid Reata's, it's overpriced for what you get.
Good italian can be found mainly in the suburbs, especially at places like Piccolo Mondo (Arlington), and great french cuisine can be found nearby at Cacharel.
Chan's Mongolian Grill(located in North Richland Hills) offers a great place to experiment with your chinese style food, especially because you can get pointers from the staff about selections and you can eat as much as you want (it's buffet in quantity, but you select the ingredients from a salad bar type setup, then get it cooked to order. Trust me, it's really, really good).
German can be found at Edelweiss, or you can spend a coupla hours driving north to Mueller, TX for bit of small town german.
Tex-Mex is found EVERYWHERE, but avoid most of the major chains. My wife and I like Posado's, but most of the really good Tex-Mex can be found in mom-and-pop places like Hurst's 'Miguelito's'. True Mexican cuisine can be found all over the place, just make sure that you avoid some of the worst neighborhoods (hint: get somebody from your hotel's housekeeping or houseman departments to recommend a place).
For Vietnamese or Thai cuisine, look to places in Arlington and Haltom City. Both offer excellent restaurants that are run by natives of the cuisine in question. Indian cuisine is haphazard, with no real center, as is a lot of middle eastern-style food. As for a barbecue favorite...I've got to go with another mom-an-pop place. Try out North Main Bar BQ(WARNING: LIMITED HOURS. The top joints for barbecue in the area are Sonny Bryan's (if you go, seek out the original at Inwood, just off Harry Hines), Railhead Smokehouse, Risky's, Colter's etc.
There is really only one great hamburger joint in town, though many claims can be staked. Kincaid's is worth every penny you will pay, because you will get a true Texas-Style burger (with all the fix'ins) at a weight that justifies it's cost. Chapp's, Ball's, and Wild Bill's all turn in respectable offerings, but Kincaid's, (get this, it was a near-west grocery store before an employee got the bright idea of firing up a grill to cook meals for the employees. The meals smelled so good to customers that they started to offer them to the customers, and then you've got your local example of the best word-of-mouth-syndrome Fort Worth has ever seen) has stood the test of time with both grace and a bit of expansion (their Southlake and La Graves Field spots make them as well as the original).
Cajun and creole are both cuisines are up-and-coming in the area. Razoo's is a solid, if not inspiring chain choice, but check with the locals for other options. Hurricane Katrina made for many a fleeing Louisiana native, and as a result, there are several places that have opened recently that feature food from the NOLA region.
