Craft beer, cheese platters and other goodness. The same company who have a restaurant in Sapa. They have a happy hour (2pm - 6pm) with buy 1 get 1 free on Pasteur Street draught beer (making it the cheapest I've seen) and wine. Really nice little place with friendly staff.
The cheese platter is great too - 180k for 3 cheeses or 250k for 5. It comes with lots of bread, some jam and a few little bits of fried fruit and nuts.
