Really huge and modern exhibition halls. There is always a lot going on here and there is actually a trade fair on every topic in every season. The admission prices are really okay for most fairs. However, eating and drinking within the fair is extremely expensive. I recommend everyone to take their own food with them if possible and to spend the money on something else.
In general, the buildings are kept modern and you can easily find your way around or ask one of the security guards.
