On this trip, I also decided to check out the business class lounge at Dubai. The quick summary is that the business class lounge is like a slightly-less nice version of the first class lounge. It offers nearly identical amenities, but just a little less nice.
The layout of the business class lounge is very similar to the first class lounge, perhaps because they’re on top of each other. The lounge is also essentially mirrored on each side so you don’t have to walk across the entire lounge to find a shower, for example (although I wonder whether people naturally head left or right once they enter?)
The business center has cubicles in it, instead of being open air like the first class lounge. I imagine that the cubicles are helpful for some privacy since the business class lounge was considerably busier than the first class lounge.
The business class lounge buffet has slightly fewer food options than the first class lounge, but it’s still quite extensive, and many of the food choices are the same. There’s unfortunately no made-to-order menu, though.
There’s also a kids room in the business class lounge. One example of being slightly less nice is that the kids room in the business class lounge had a PS3 to play, while the kids room in the first class lounge had a PS4 (I didn’t even realize this was a thing, which shows you how behind the times I am).
There’s no dedicated relaxation room in the business class lounge, but there are reclining chairs scattered throughout the lounge with blankets on them.
One thing that I appreciated about the business class lounge were that there seemed to be lots of hidden seating areas. So you might be able to find a small, cozier section to have to yourself.
If you go to the far ends of the lounges, you can go downstairs to the “quiet lounge” areas where there are donuts. I don’t think that many people make it that far as the lounge attendant working in that area seemed quite surprised to see me there.
Overall, the business class lounge is just like a slightly less nice version of the first class lounge. The lounge offers all of the amenities you might expect from a business class lounge, and there’s plenty of space and seating, even though there are more passengers. If you’re looking for a quiet place, I’d say try going to the far ends of the lounge, since the lounge is so big that most people probably don’t explore the whole thing.
