The service staff always use hand gloves when they serve golgappa. You definitely have to stand in a queue if you visited the chain in rust hours like 12pm to 3pm or 7pm to10pm.
The only drawback I believe this chain in comparison to other chain is not enough seating facility. Rest as per food is concern its awesome. Try it you will love Dilli ki street food
