Yep, I expected to see nothing for Phnom Penh, Cambodia, but there were actually quite a few useful results. It's a least comparable to the one hand-curated events site for Phnom Penh that I know of.

I did have some odd UX issues with the filter button. Sometimes I couldn't tell if it was responding to my input, and once or twice it reset the options I selected back to what they were previously. But, keep going OP!
