This is your average grocery store, except one bonus feature - a single bin between the Lindt chocolate and the liquor section that contains heavily discounted miscellaneous items such as -- drinking chocolate powder from Ghana, veggie bouillon, sauerkraut (obvi), mustard, gigantic tubes of mayo the length of my forearm, etc. there's also a general household section that actually is cheaper than the 1 Euro store downstairs for some items, so I recommend checking it out before beelining to the 1 euro store for goodies like candles, nails, twine, etc.
Most of the shop however is bizarrely organized (why are the eggs not close to other dairy products...) and there aren't that many options for things, which perhaps is a bit of a relief. I have discovered that the "international" section is much larger than I believed and you can find a huge can of chickpeas from Indonesia or something that is a much better deal than buying the REWE brand chickpeas. Also the ja! Brand is awesome for prices but tends to give you less quantity, apart from the rice. No other brand carries as much rice.
The cashiers are less sad than at places like Aldi, but they are also very busy because the place is always popping with people. Will note that the candy section in the a club corner feels dark and has a cool cult vibe, that vibe of when you are willing to buy 100 count rolls of chocolate cookies and don't care if others see you trolling the discount candy section read more
