Don’t know about others but when you visit Hyderabad Gokul chaat is the best place for chaat eaters. Road side chaat trollies are not safe in this covid time. It’s harmful. I suggest It’s better to make at home and eat than purchasing and putting yourself into trouble. Believe me I’ve experienced it. Bombay is also one of the most known place for chaat. There you will find chaat bandi step to step. Have a good luck.
