I've always been intrigued by coffee syphon coffees but i'd love to go try one before I invest in gear. Is there anywhere in perth(preferably near cbd and open weekend) that I can go to try a coffee from a syphon?

Side note....Whats the deal with coldbrew? I've done it a few times at home in the aeropress and it just doesn't excite me and is too weak for my liking. Anywhere in Perth that does a good cup of that too?
