I haven't been to Dallas in many many years, not since I was a wee little baby with my just fresh off the boat parents living in good ol' Oklahoma. I visited Houston before just last year, but with Texas being so large I might as well been in another state. Dallas is a fascinatingly designed city, though somewhat predictable, with its huge ass sprawling highway network and sea of cars. Food is an anti-vegetarian delight; the amount of beef I consumed in a 3 day period was the most I've ever done, ever. Dallas does have the most generic Texan things ever like people with the Texan twang accent and cowboy hats (so many cowboy hats!).
The city, as expected, is massively spread out with the most confusing highway system known to man connecting everything together. Getting from one place to another means dealing with rush hour traffic durning non rush hour times and figuring out how the damn highway network is connected to one another. I can't tell you how many times exits are way too close together which confused me into taking the wrong exit. I mean it makes sense for Dallas to be designed this way as gas is cheap down south and Texas is mostly just flat land... and there's unlimited land from whichever direction you look at. There are soooo many cars though and I rarely saw any public transportation systems. It's like Dallas said "fuck the environment" and went with the most auto-friendly design possible.
Beef BBQ is an incredibly great Texas experience. The few highly rated places that I went to in Dallas never failed to meet my expectations. Imagine biting into the most tender and flavorful (but not too overwhelming) piece of beef, that's what it was like eating at every single BBQ joint we went to. And it's not just the traditional Texas style BBQ food that Dallas has, but also the Mexican and the Tex-Mex. I have no idea about the authenticity of those foods, but the food I did have was damn good. We also went to a somewhat fancy steak joint and had a pricey steak and boy do I have to say, Texans do not mess around with beef cooking.
I wouldn't say Dallas is one of the more diverse cities that I've visited; it was easy to tell which part of the neighborhood we were at or the typical patrons of whatever restaurant we were in. The most diverse we saw was at the Dallas arboretum but I suspect most of them were tourists anyways. However, all the people we interacted were very friendly. The food was great, though it actually made me dearly miss vegetables for once in my life. I would say Dallas is a great weekend trip city; there's enough things to do, see, and eat, but realistically it'd be a big adjustment to make if I ever wanted to move there.
