Overall, the LoLu is a good place to stop by if you're in Duisburg city and need to get something to eat. No meat served, some ovo-lacto dishes, though, but labelled as such.
I really enjoyed most of the dishes although my tastebuds sometimes suggested to me that some items may not have made homemade.
It's a cozy setting, most of the time, staff is really nice. Could be a bit more attentive at times.
Overall, I always enjoy my food/time there.
Cons: service can be improved
