The Coco Café Sugar Lounge is a delightful shop, the sort of shop that thrives in Petworth. One of the great things about Petworth is that it is too small to be of interest to national chains, but is still the home of interesting outlets like this one. Other examples are Guilt, Courtyard and Artful Teasing - all of which stock goods that you can't easily get on the standard high street.
It sells chocolate and sweets, but all interesting and unusual brands that you wouldn't find in a newsagent. Some of them you may have heard of, but some are really small chocolatiers that I frankly don't know where else you would find them. For instance, they stock the local chocolate produced by the Chocolate Alchemist.
You can also have a cup of coffee there if you are lucky enough to get in when one of the few tables are free. If you want a more traditional café with more seating space look for Tiffins.
They are good at promoting themselves too.
And they have a website

12.4.09 Update - they have opened up some more floor space now so there are a couple more tables.
They also do art exhibitions, for example Claudia Jones at the Coco Cafe Sugar Lounge Petworth.
