I stopped in at Chuao for a mocha at lunch.
I think these guys have the best mocha around. This is one of the most intense versions I've tried - unlike many including the Valentino Chocolate place at The Spectrum, you really taste the richness of the chocolate, there's no skimping on the good stuff.
I got their signature traditional mocha, as opposed to the aztec/mexican chocolate version I'd tried previously. I think I favor the traditional version most, for the simple reason that it's more of a pure chocolate experience !
