Depends on which lounges you are used to. Compared to many other contract lounges in the world I find the Al Reem lounge above average. They serve quite tasty hot food and provide all the services what you would expect from a contract lounge.
On the downside, it is often overcrowded and has not enough showers and restrooms. The EY lounge is of course a considerably higher standard, but compared to a couple of other (contract) lounges in the world, I find the Al Reem not too bad.
Thanks. That is assuring. Maybe everyone compares it with EY premium lounges.
