So I finally managed to check out Sparkle - and can report that it's definitely serving authentic Chinese food and not bland north Americanized fare.
Smoked chicken was tasty - but be aware that a half bird is just that. Literally, cleaved down the middle, lengthways
Definitely an authentic Chinese experience. I had a great minced pork, chilli and vermicelli thing that was called "ants on rope" or something similarly poetic, really hit the spot for me. The chefs special aubergine dish was also good, perhaps a little oily but the taste more than made up for it.
Dim sum were pretty good, just wish you could order a mixture instead of 10 of a particular kind (maybe we'll ask if we can do this next time...)
We happened to go with the in-laws on Sunday afternoon and it was dead, but still had some great food. Definitely going back, and hope that Hamilton gives this place the trade it deserves so it can become a welcome fixture.
