Run by Do Thanh Long, Banh Canh Cua Ba Ba (Mrs Ba's crab rice noodle soup) has been bustling after the French food guide included it in its Bib Gourmand list of good-value eateries.

The eatery, situated in a four-meter-wide alley at 84/6 Nguyen Bieu Street, Cho Quan Ward, opens daily from 8 a.m. to 8 p.m. Visitors can follow the signs to reach it from either Nguyen Bieu or Nguyen Van Cu Street.

The soup is a thick orange-hued broth made from crab roe and served with fish cake, claw meat, and shredded egg.

Servings start at VND55,000 ($2.10), while a clay pot, designed for groups, costs VND120,000 ($4.60).

The broth simmered from pork bones has a thick consistency and is refilled throughout the day.

Toppings displayed in a cabinet include shrimp, crab meat, pork skin, quail eggs, fish cake, and pork.

The ingredients are made by his family members from early morning.

Long manages operations, his father oversees the broth, and his siblings serve customers.

He says even before the Michelin recognition, the shop got hundreds of customers daily, and now business has grown by about 20%, keeping its 10 staff busy.

Quynh Giao (R), 22, has ordered the clay pot version with friends. A regular who visits every week, she says the portions are generous and the price reasonable.

"I love how thick the broth is, with that sweetness from the crab and bones."

Foreign tourists make up about 30% of the shop's customers.

Delfi, a tourist from Singapore who learned about the spot through social media, decided to visit as she was curious about the Michelin title.

She is all praise: "Michelin made a fair choice. The food is delicious, beautifully presented, and a great experience."

All the employees wear non la (conical hats) while serving, a touch that gives the shop an identity.

The busiest periods are at around 11 a.m. and in the evening.

On online platforms, the shop has a 4.6-star rating, with lots of positive reviews about its quality and service. Free parking is available.

However, since most of the seating is outdoors, it can get hot, and customers often face long waits during peak hours.
