I agree. I always thought the two-building approach was madness—put the best shops into one of them and the other into a food hall, maybe a concert venue, or something else.
I'm hoping something might happen eventually, as it's crazy just to leave it sitting there now covid is largely behind us. Might be an idea to have a Promenada thread?
Getting back on-topic I'm not in love with airport plaza personally and think Festival knocks it for six - it's just too old.
