If you're local and have been here a while, you might remember Stiles Farmers Market on 52nd Street. It had the best cheap produce in HK and was always busy. I'd been buying from them for years, but in 2019 the building next to them was condemned and they had to shut down their business while the building was demolished. Luckily they have another location on 9th and 37th. Although it's a bit of a haul from me, I'll make the trek as I like these guys and their produce is fresh and substantially cheaper than anything you'll find at The Food Emporium, Amish Market or Target.
