Anh is a really cool guy - his big brother and him have various good big bikes for sale - he just opened a new bar: Offroad Bar (200 Pho Duc Trinh - on Yen Phu going South once you have passed the Sofitel Plazza, the Ilu Building and the road that goes to the Truc Bac area, right after the gas station make a right and the small street that is parallel to Yen Phu is Pho Duc Trinh - one can actually see the Offroad Bar sign from Yen Phu), a very cool and fancy bikers bar with well designed furniture made of raw and recycled materials such as oil tanks - the crowed there at night is pretty fashionable while afternoons are more relaxed. An area of the bar desplays a few motorbike gears/accessories such as bike clothes and cross helmets, and a very good condition Honda CR125cc which is for sale. The waitresses are friendly and the bia toi (Halida) is always fresh.
