They stock several vegan options, but you still have to read most labels. They have a bakery that sometimes has vegan treats (the last few times they've had nothing, but they're delicious when they do). I buy a nice coconut based shredded cheeze there and nice soy cream cheeze. Otherwise, I go for dips and crackers and cookies. The produce is nice, but a bit too prices so I only buy rare items they sometimes have like today I got charantais melons, but paid nearly 5 euros each.
I buy my shampoo, conditioner and soap there, the only clearly labeled vegan and no perfume option I've found in Stuttgart - Urtekram.
I always shop there before a trip and stock up on vegan fruit and nut bars, or even candy.
They also stock some baby products I give for gifts.
I'm glad we have this option in Stuttgart, though they are still often out of stock, but I find this is typical for German markets.
Cons: still have to read most labels, closes a bit early, often out of stock
