No. You can purchase concessions at the American Airlines Center. Plan on being in the convention venue for 7 hours.
All Food and beverage kiosks on both the Plaza and Terrace Levels will be open during the two days of programming. Concession sales will be available from when doors open until 30 minutes before programming ends each day.
Please note that alcohol will only be available for purchase on the Terrace Level and will be sold from doors open until 7:00 PM. No alcohol will be available for purchase on the Plaza Level.
