De Pijp has a new Vietnamese restaurant! Yên Dining Bar The restaurant on Van Woustraat is open six days a week for Vietnamese delicacies. Lunch is (currently) only available on weekends, but hey, there's a good reason for that: extra focus on the quality of the dinner. And believe us, you can taste it. From fresh summer rolls to savory pho and those indispensable summer noodles… everything is made with love and just that little bit different from what you're used to.
