Head north up Swanston Street until you get to Bourke Street. Then turn west (through the mall). Pancake Parlour is on the south side. Tram up Swanston works well, or you can walk, it's not particularly far (unless you have a condition that precludes walking for a few hundred metres.)

As for the RSVP (to dalekboy): sorry, I'm planning on being six feet under for most of the weekend. (Water, that is. What did you think I meant? :)
