as cliche as this answer often is: I miss the food and drink most - never quite had anything like it since i left (e.g: bartending just doesn't seem the same on average anywhere else I've been).
so I last 'permanently' lived there in 2013, worked in Dubai for almost 3 years after that and now finishing off my MSc in the UK for the past year.
(edit: to add: I'm from there - so i go back often and get my food fix)
