We had the great pleasure to dine in at Sattgruen's Flingern location four times during our week stay in Dusseldorf, we were hooked right from the get go.
The food was consistently great - each dish of the buffet-style array was done perfectly and the variety of choice meant that everybody could find something to their liking - as was the service, most of the staff members were exceptionally kind and patient with us.
We especially want to thank the super kind waitress who called a taxi for us, thank you for helping us lost, non-German speaking tourists!
The atmosphere and vibe were very welcoming, and thumbs up for being pet-friendly, we noticed a few canine friends hanging out by their humans. :)
As to the best part, it has to be the memorable mushroom dish, we're still trying to figure out just what the chef did to make those delightful fungi taste so magical...
The one and only negative - no credit cards are accepted here, but as I understand it, this isn't to be unexpected when dining out in Dusseldorf, some cafes/restaurants choose to be cash-only so be prepared.
That aside, the verdict is:
Highly recommended for all, and please do try the mushrooms if you're so inclined, they're just that good!
P.S. For those with sensitive tummies: dear friends, I had no negative reactions to report which is a miracle in and of itself (eating out is always a double-edged sword for me and my tummy), so do not fear trying out the numerous soup, salad and hot meal combos - what's more, the main ingredients are neatly listed above each dish, in both German and English, so its easy to steer clear of any problematic foodstuffs. :)
Cons: no credit cards
