There are many different places where you can purchase everything needed for starting and running a successful cafe. Start is by looking at local stores first - be sure to check commercial grate catering stores which will have plenty of supplies. If you're looking for supplies online, I recommend checking out Amazon first. They have an extensive list of suppliers (both large and small) who sell everything needed for running your new cafe business: coffee machines, espresso machines, food slicers, blenders, and all kinds of stuff. Aside from that, try Nisbets, or even going directly to the brands like Rational.
