Apsara is one of the easiest and most delicious go to Vietnamese places at Croix de Chavaux. The menu is simple and includes soup with noodles (natural or curry based), bo bun, rice, chicken skewers, hot tea, mochi, che chuoi (banana with coconut milk and tapioca pearls), etc. The food is very reasonably priced; one can eat for less than 10 EUR. There is normally a line during lunch hours, for good reason! Service is friendly.
