This is, with out a doubt, one of the top 5 eating establishments in Aix. Yes, that's right, one of…read morethe top eateries in Aix is Vietnamese.
It is a very small restaurant. I do believe they have one table, so the food is almost always "to-go"'. It's perfect during Spring, where you can sit on a fountain, or in the park, and enjoy the wonderful weather and Nguyen Thanh's culinary perfection.
The food here is perfect, and the owners ensure this quality with painstaking detail. The food is very fresh, light, and flavor-blasted. As with the other reviewer, I also suggest the "Magic Bo Bun".
When your food is served, they take great care to make sure an even and perfect proportion of meat, vegetables, noodles, and sauce is given to each customer, and they ladle your food onto your plate with such care and love. This is perfect and must not change - it is what makes this place so special; however, I must warn you, eating here is a test of patience.* And I'm not talking about American fast-food patience - I know many French who have given up on the wait, but it is worth it. If there are 10 people waiting in line for food, you will be waiting for 20-30 minutes, so bring a book or a friend, because a little extra time shouldn't keep you from some of the best Vietnamese food in the world.
*Note: The last time I ate here was in 2008, so I'm not too sure if the long wait still exists.
