Made my friend upset. What did I do wrong?

I don’t understand what I did wrong. I went to visit a friend. I just moved half way across the country for a new job. My friend lives in the next state over, which is great to have someone nearby. She also just started a new job in her hometown. She randomly started catching an attitude with me, when I just asked if she made any friends at her job.

She said how there’s not many people her age who work there. I found that a bit strange and just said something like how strange that was because she lives in a city, that has a large population of people our age (late 20s) , but I’m sure she would find friends soon outside of work.

I mentioned how there’s a ton of people at my job the same age as us, which I explained was a relief to have (after working in a company with college grads). I’m not sure if that triggered her, but I sensed her starting to make my job and new city, seem small and beneath her . She said something how when you’re in a bigger city, things are different and a lot of people stay there longer, which is why they didn’t have much young people.

She started calling my new city, a small area & said that’s why I had so many young people at my job. She said my job was small and smaller companies tend to have younger people. How when you move to a bigger company like hers there’s more mature people. I was confused because I brought up companies in cities bigger than hers, that I new for a fact had people our age. She dismissed it.

She said how I need to get out more. She also gave a backhanded compliment when I mentioned how I liked the scenery in her city, and she said that it wasn’t a big deal, because she sees this everyday and how she’s happy I came to visit so I can experience what a true city is like, and not get excited about what I see in my new place. I’m from a small town, so while my new city is bigger, it’s still relatively small compared to larger metropolitan cities. However, it’s still a huge upgrade to me.

Later on, I just brought up how the food in my new city, wasn’t anything compared to my hometown . Which is in Louisiana , I’m in the Midwest now so there’s a huge difference in culture especially food. I named a signature dish in the new city, that everyone I met didn’t find that appetizing. I was just making a joke, like “you can’t expect much, when the most appetizing thing they have is this. I really miss my moms home cooked food.”

Mind you, she’s never been to this new city I live in, before or even tasted the food there. I was just describing it to her and she said “Louisiana has nasty food too & started describing a dish she tried that tasted like shit and that everyone said she should try it.

I was confused on what she was referring to, because she mentioned a dish, that’s not what Louisiana is known for. She kept getting annoyed with me when I didn’t understand and I she said “I was saying that just to let you know that there’s nasty food everywhere & Louisiana isn’t a place where everything is good

After that she was really distant and I didn’t understand what her deal was.

Did I do or say anything wrong? I could understand if I said something offensive about her hometown, but I was only referring to a city I live in now, that she’s never even been to before.
