Pretty nice for a smaller airport lounge, especially when you consider MIA is not a Delta hub. Everything was clean (didn't have a chance to use the showers).
I was impressed with the staff's patience in handling one exceptionally rude customer who held up the check-in line.
One complaint is that it was a little hard to find, but maybe that's the idea?
Nice snacks and drinks.
As other posters have pointed out, FT was the only non-French publication available. Not a complaint, just an observation.
