One of the largest and busiest grocery stores on Newark Avenue (India Square). On a street with over 10 grocery sores, cutthroat competition, and perishable foods, Patel Bros has managed to survive for decades, growing and doing well.
I think it's because they carry everything and the groceries/veggies/fruits are the freshest. There is a really high turnover of products, so I feel confident that whatever I'm picking up is not old. The operation is run like a small American supermarket (not a fobby Indian place) and the staff is plentiful if you need help. They eve help you find stuff and carry your purchases to the car (usually without prompting).
They carry all the Indian veggies and groceries, but also things I used to have to go to Shoprite for. How convenient. Now I can do all of my shopping in one trip. They also own a couple of locations so I think they do bulk buying, which allows them to sell at low prices.
