They will feature 11 types of noodle dishes from northern, central and southern Vietnam.
Expect chicken and beef phở, and other dishes such as rice vermicelli in a crab and tomato broth, and egg noodles in duck curry.
The noodle bar will also offer six variations of bánh mì or Vietnamese baguette sandwiches, with fillings that range from cold cuts and pate to grilled chicken and pork meatball ($5.90 a serving).
The new concept’s first outlet will open next month on the basement level of Raffles City Shopping Centre.
The 50-seater restaurant will take up half the space currently occupied by Canele Patisserie Chocolaterie.
Both Annam and the Nam Nam Noodle Bars are part of the Les Amis Group, which runs patisserie-restaurant Canele, French restaurants Au Jardin and Bistro Du Vin, and Italian restaurant Peperoni Pizzeria.
Nam Nam means yummy in Danish, a language the chef speaks fluently – he grew up in Denmark – and is a take on his first name.
Noodles will be priced from $7.90 a bowl.
The restaurant will also serve dessert, Vietnamese beer and coffee.
