New York City’s viral diner is a family affair. See how dad, mom, brother and sister took Datz Deli from $300 a day in revenue to $7,000.

• Datz Deli of Queens is a family business making headlines for its unique menu items.
• It’s home to the Dat Mac Patty, a Caribbean beef patty sandwich stuffed with meat and mac and cheese.
• The family-run deli has sold more than $300,000 worth of food in the past two months.

In Queens — like many other New York City blocks — there’s a family-owned deli on the corner of Hollis Avenue. But this one’s unique food is projected to bring in more than $1 million in earnings in its first year open.

I visited Datz Deli last month after witnessing more than a few viral posts gushing over its monstrous, yet delicious-looking, stuffed Caribbean-style beef patty sandwich.
