Meet Chef Oscar

The hands behind every plate — Naples-born, family-trained, Dublin-loved.

Chef Oscar Bertone

Oscar Bertone

"I cook the food my mother and grandmother taught me. That's it. That's the whole secret."

Born in Naples, Oscar grew up watching the women of his family cook — slow ragù on Sundays, fresh pasta hung on chair backs to dry, pizza dough proved overnight in the kitchen window.

After years cooking across Italy, he brought those same recipes to Dublin and opened La Cosa Nostra on Thomas Street: a small family restaurant where the food is honest, the welcome warm, and every dish made to order.

You'll usually find him in the open kitchen, sleeves rolled, shouting good-naturedly about the dough — and stopping by your table to make sure the risotto was right.

Hey, welcome in 🍷 I'm Tony. Tell me what you're in the mood for — date night, family dinner, takeaway — and I'll point you the right way.
Heads up: Tony's got a mind of his own and sometimes runs his mouth. He's been known to embellish, flirt with the nonnas, and swear on his mother over things he just made up. For actual bookings, prices, allergies and anything legally binding — call the restaurant. Capisce?
