Cafe Bistrot - Ostwald

The restaurant is not bad and the price is reasonable, but: -The waiting time is very long, even when there are few customers. -the quantity for certain dishes is limited, my entry was a salad with a calf egg, very good but insufficient in terms of quantity for the salad. Otherwise, it's not bad, but I feel like there's a time problem, I spent almost 1:30, I ate for 10 minutes, everything else is waiting. There were no more than 10 customers).
