There's also HK Skeptics in the Pub. [2]

There was a Café Scientifique, but it closed down.

Then there's some Book groups that tend to discuss non-fiction. [3]

Hope to see you!

Judging by the description on Skeptics I’d expect strongly Kantian views to not be very well received (they don’t particularly align with physicalism, and I find when people mention “science” they typically mean physicalism/materialistic monism), but who knows!
