Why people come back
The Petit Sao of the South Shore
On rue Saint-Charles, steps from the Longueuil metro and the cégep, the restaurant serves the same menu as the Montréal Petit Saos: large chicken pho for 17.50 $, grilled chicken banh mi for 13.50 $, bún bowls, imperial rolls and Mama Thi's nems, lunch menu for 17.95 $ Monday to Friday.
What is different here: a real bar list with 20 cocktails, and continuous hours, every day from 11:30 to 21:00, Sundays included. Book online for dinners with friends and nights out on rue Saint-Charles.
It is also the kitchen that prepares catering orders for Longueuil, Saint-Lambert and Boucherville: lunch boxes for offices, buffets for family celebrations, without crossing the bridge.
