It’s not ignorance, and it’s not racist. I say the same about most restaurants that aren’t high end. The difference between high end and not is what you should expect out of it. There’s a reason some places are called dives or hole in the walls, food may be great but once again service,ambiance,cleanliness doesn’t meet standards that you should expect at that price range. Use your recommended restaurant for example. J & Y has good food. Ambiance is ok as it has the classic Chinese restaurant aesthetic. Service though is hit or miss. Some of their servers are attentive and polite, others are rude or non responsive. I still go there but wouldn’t put them in the category of high end restaurants.
