As soon as I saw their menu I knew it was not the authentic Vietnamese fair that I had expected. My…read morelocal friend in Stuttgart suggested it, as it got good reviews - very possibly from people unfamiliar with Vietnamese cuisine. The waitress explained to us that when they first opened, they did offer authentic Vietnamese dishes, but the locals weren't interested, and the business got so bad that it faced closure. Since they have edited their recipes to meet the local taste, they are doing roaring trade now. Unfortunately for me, it was just about the worst meal I had during my multi-nation trip this summer - Switzerland, Germany and Ireland ... seriously, these three countries aren't on top of the list in the culinary hall of fame, but they all did much better than this Vietnamese representation! Their pho came with dark brown sweet potato noodles, instead of the usual white rice noodles. I suspect that it may be hard for them to get authentic ingredients, as all of my vegetarian choices featured the same things - mostly just Tofu, even seitan, which doesn't belong to Vietnamese food. I was super stuffed (and bored) with soybean protein that night. Their outdoor seating is pretty, but during the heatwave, not having indoor AC was also a down side.
