Aldi’s does not own Trader Joe. The owners are cousins, and I’d guess the Aldi cousin is the poorer one. Anyway, Aldis now has a few stores (at least one I know of) in NYC. It’s real hit and miss insofar as kashrus. For example, they had a really tasty microwave popcorn in their Clancy line with an OU. Now I can rarely find the OU, apparently comes from a different plant. But decent produce, very good prices, strange brands that you’ll never see anywhere else.
