Visited once. Very popular place. It's the first place that I've been to for ages that not only has other foreigners but also an English menu. It seems like it's been featured in some guide books and most importantly, it was visited by Anthony Bourdain which always makes a place popular.
The bánh xèo was nice but at 70,000d it was over double the price of other ones I've had that were just as good. Lots of shrimps though. They also make you pay for green tea and parking (5,000d each) which are normally both free. I guess that's what happens when somewhere becomes touristy.
