We ate at de Kelder on two occasions and were pleased with the food on both occasions. On neither occasion had we booked, but they could find us a place. Portions tend to be large; a salad starter is almost big enough for a main and the main courses are similar. Glasses of wine are similarly large at 250ml.
The food is good; a beef fillet ordered rare was red and lamb ordered as pink was pink. Everything is reasonably priced and the service is smooth and efficient.
