Most of us will only be going for the Test series, which doesn't start until well after Ramadan's finished. I'm pretty sure that there was no bar there last time I passed through (about 4 years ago), but Qatar Airways isn't a dry airline (or at least it wasn't then), and I've heard that Doha airport has since been expanded, so I was hoping they might have seen fit to open a bar.
Anyway, thanks for the advice.
