The light festival does look fun but they were really strict about letting people into the inner area of the city. If you didn't have a ticket you didn't get past the barriers.

I had to look up pomelo because I'd never heard of them before. They're apparently one of the ancestors of grapefruit but it sounds like they're really sweet and not bitter at all. Please tell us what you thought of it!

That does sound like them. I liked it, it did have a grapefruit feel but without the sourness. I'm not sure if I'd go out and buy one, as interesting as it was to taste I much prefer oranges if I want something citrus. But as a one-off, I'm glad I did try it.
