There is a reason why the Finnair Platinum Wing is Emerald only.

The far majority of business class lounges rely heavily on self service, and will continue to do so unless you want to reduce the footfall to first class lounge levels. I am probably more for a self service lounge, than a table service lounge where there is no option to be seated quickly or you can't have a quick bite as you have to wait for service. In a too busy lounge, things just get worse if it has to be serviced.
