This stone is from Chinatown. It is a must visit for the food alone but here is a pro tip for you. You really need to watch your belongings because no matter when you go the crowds are massive and the streets are narrow. It is very easy to get distracted while you are exploring.
That said the energy here is unmatched so find a hole in the wall spot for dumplings and soak in the most authentic slice of the city. My absolute favorite is getting dim sum over at House of Joy.
It is one of the few places in the city that still feels authentic and untamed. Just do not look at the map and instead follow the smell of sesame oil to find your own secret spot.
