Even in NY, the traditional "American" food carts sell hotdogs, pretzels, ice cream or $1 pizza. All of which are IMO, pretty sub-par for street food. It is only since halal carts became a thing, that NY street food has started becoming alright. There are some other great food carts, but 1 off carts get overshadowed by the dozens of familiar NYC foods.
US's culinary strength lies in the diversity of cuisines. However, most affordable international food places are not opened by aspiring chefs. Rather, it is usually struggling immigrants who use it as a way to survive in the absence of other employable skills. While I respect the hustle, these people can obviously not cook at the same level as ones that run their operations in their country of origin out of more passion driven reasons.
When American born people with a passion for cooking start affordable restaurants in the cuisine of their roots, it is often heavily colored by their American upbringing. (which for me ends up meaning more sugar, more fat and less intense flavors) Not gate keeping, but at the end of the say the experiences of someone fully immersed in a culture will always be richer than those who've vicariously experienced them.
That being said, for every cuisine in every big city in the US, there is a gem. They can be hard to find, are often not the most accessible (non-commercial area, language barrier, sketchy hygiene), but damn are they worth it. The ability to have a gem for each cuisine of the world, is a trait possibly unique to the US metro cities and their biggest strength.
I visited Portland a few years ago and the quantity and quality of street food being offered was amazing. There were entire squares packed with vendors.
I enjoy the street food scene in London, but I'd choose Portland over it any day.
In China, street food might cost 20 yuan for a dish of something. The median income for all of China’s is 18,000 yuan.
In Portland, the median income is $53,230. A street dish might cost $10.
In China, street food is actually a lot more expensive than Portland, adjusting for median income levels. Even if you bought a dish for 10¥ it is still more than twice as expensive as Portland.
Are we to say that China’s street food ain’t street food? Because that’s what you are suggesting which basically means that no street food is street food.
I meant if it costs the same as a restaurant, it's not cheaper and thus I wouldn't call it street food. I wasn't comparing across cities. If a decent restaurant decides to ditch their downtown indoor restaurant, and decide to get a food cart and offer the same food for the same price as they did, is it really street food?
A number of popular food carts in Portland have a median price of $10 or above. For things like Mediterranean food I've often found restaurants charging the same or less. At the end of the day, I'm paying for the privilege of standing in the cold/rain.
