Where to buy a Phin/Vietnamese coffe filter near Xuan Dieu street?

Hey everyone,
I've been working out here for a couple of weeks, staying in the Sherraton hotel, and am heading back to England on Sunday morning. I bought some some coffee a while ago but forgot to buy the filter, stupidly - do you guys know anywhere that would likely sell me one around my area?

Thanks,
Jerry

If you have time to pop into Vincom mall in Ba Trieu street go to the supermarket Vinmart, they sell coffe filters there.
hope you have time.

I see some trung nguyen coffee shops sell their own good filter. You can ask at these place. I hope you have one early
