First single-dish restaurant to open in SA

A decades-old family recipe will be on the menu when Australia's first single-dish restaurant opens its doors in Adelaide on Thursday night.

Spaghetti Crab will offer diners just that - one pasta main, no entrees, no sides.

The dish, which is made using fresh South Australian blue swimmer crabs, has been refined by local restaurateur Carmela Ventura.

"I have cooked this recipe for my family and our friends for over 50 years, and I am so excited that I can share our family tradition with Adelaide," Ms Ventura said.

"While it looks like a simple meal of spaghetti and crab, the flavours, the sauce, the perfect spaghetti, combined with friends and family sharing in the meal, remind me of our family table."

The restaurant is the brainchild of Ms Ventura, her husband, Vic, and colleagues at their nearby Italian restaurant, Ruby Red Flamingo.

In keeping with family tradition, the spaghetti will be drawn in generous portions from the same dish, with an extra side serving of sauce in an iron pot.

Guests are encouraged to lay their crab shells on paper-topped tables, making as much mess as necessary.

The only decision will be made on the wine list, with three Italian wines chosen to accompany the dish.

Spaghetti Crab is expected to be open for six weeks at 47 O'Connell St, North Adelaide.
