The specialty is a Vietnamese soup called Bun Rieu. Bún riêu is a traditional Vietnamese soup of clear stock and rice vermicelli.
There are several varieties of bún riêu, including bún riêu cua, bún riêu cá and bún riêu ốc. Bún riêu cua is served with tomato broth and topped with minced freshwater crab.
The one here, and the one we came for has a crab paste for its base broth, and is stocked with vermicelli and a different assortment of meats, each with its own texture (texture is an important component of most Asian cuisines).
Friend Thomas had heard about this place through friends, visited it, loved it, and we all found an opportunity to dine for lunch. I absolutely loved the soup. The only thing I passed on (removed it) was the cube of blood jelly.
Very little English, so we pulled out our trusty Google Translate apps and had no problems.
Yep, there are more things to choose from on the menu but I'd go for this soup on your first visit.
