This lounge is for non-Star Alliance and non-shengen area flights (e.g. Qatar etc). This lounge is located in main terminal area before the passport control so if you are transferring from non-shengen to non-shengen country, you won't get to use it unless you go out via passport control and back in. That being said, it's not that worth all the efforts.
Mid-afternoon, there is only fruit and crackers as food and some drinks (not good coffee machine). Perhaps it's better to swing by at breakfast/dinner time. read more
