Where Is The World's Busiest Trader Joe's Location? - Tasting Table
Briefly

Grocery shopping in New York City differs significantly from the experience elsewhere, mainly due to space constraints and the busy urban environment necessitating smaller shopping carts.
The Trader Joe's location at 72nd Street and Broadway is recognized as the busiest in the world, featuring two floors and numerous checkout counters to accommodate high foot traffic.
Despite the long lines, customers often praise the store's service, noting how employees maintain a fast-paced checkout experience, thanks in part to having more counters available.
Trader Joe's has adapted to New York's urban lifestyle by providing multiple locations and extended hours to meet the needs of its diverse and densely populated customer base.
