Difficult Order

Pasha went out for dinner with his friends Sasha, Dasha, and Natasha. Pasha took place in front of Natasha. Sasha took place to the right from Natasha right in front of Dasha. When the waiter came up to take the order, Sasha and Dasha ordered steak. Natasha chose fish, and Pasha (who is fond of riddles) made an order this: "Unless the man to the left from the man in front of the man who ordered fish doesn’t have what the man in front of the man to the right from the man at my left has, then I'll have what the man in front of the man to the right from the man in front me ordered. Otherwise, bring me the kebab."

You were sitting at the next table and decided to help the poor waiter. Assuming that "to the right" and "to the left" was from the viewpoint of the diners, tell the waiter what did Pasha order?
