No Winterthur staff member knew Brunch procedures. No one was available to register or seat us, when we arrived. The chef was rude, insisting we needed tickets. One cafeteria customer had to stand with her tray while the tablecloth was pulled off her table, before she was allowed to sit down. Service was spotty and we had to request the check to pay. The food was delicious. The other staff members were very pleasant, when we encountered them.
