MZC is a common abbreviation for the Mezzanine Club at Oracle Arena. This is a prime seating area located just above the 100 level on the north end of the arena. There are three rows of seats in the Mezzanine Club, often labeled R1-R3. While these seats don't provide great views of the game, ticketholders enjoy such benefits as all-inclusive food and drink.
