Can we get kegs filled/exchanged here? Or does that have to be done elsewhere?

I don't know about costs, but the selection is quite good. Porters on tap through IPAs

I swap kegs out all the time here, no problem!

Awesome! 2 follow up questions then: is it cheaper there than other places to swap kegs, and do they have a largee selection of available beers, aside from the standard IPA and 90 Schilling
