Im keen, so some places to choose ; depends on how many people & how lazy / far u want walk :
Bavarian (rocks) - breakfast tradition ! all imported - ask for the Maibock !! (u might get lucky!)
Lord Nelson (rocks) - all local brews
Harts (rocks) (lunch?) - 4 local + 4 guests, 2 handpump
King st Brewery (Darling harbour) (lunch?) - 4 or so local brews plus Matilda Bay brews etc
SG aka Spooning Goats (York st) - has 4 beers on tap, usually a few Riverside
Royal Albert (Surry hills/central) - has 8 taps always changing & burgers / dumplings
Local Taphouse (Moore park).... ?
Rocks Brewery (Bourke rd, Alexandria)
Quarryman (Pyrmont) - about 20? beers on tap
Lord Raglan (Redfern aka Rocks Brewery) - 8 local, 8 guest ?
Young Henry's Brewery (Newtown) (closes 7pm) - 4 local, 2 local handpump
The last 4 are outside cbd but could be the last stop ....
The last two are near train stations ....
From previous experience, less is more, so 5 or 6 stops is a good number, depending on your stamina
