Introduction
It's the sequel to Portal. You make portals and use them to solve puzzles.
Gameplay
You make portals and use them to solve puzzles. Fucking brilliant puzzles. There are some new elements to wrap your head around, which are used is some genuinely clever ways. I would say in general, some of the puzzles are harder to figure out than in the first game, simply because of the added elements, but I was never stuck for so long I wanted to quit playing.
Sights and Sounds
The benefit of making a game running on Source is that any decent GPU can run it maxed out. I was getting butter smooth FPS at 1600x900 with 16xQ CSAA, 16x Anisotropic Filtering, and all the options to the highest settings. Also, the textures, models, everything about the way it looks is just right. Sure it's not as "photorealistic" as say Crysis, but it's definitely the best looking Source game ever. The gels in particular look fucking gobsmackingly good.
Voice acting is top notch as usual. Glados, Wheatley, and Cave Johnson are a constant source of pleasure.

Conclusion
Holy shit. Best game I've played all year, and I've only done the single player. Valve has delivered a masterpiece, as mindblowingly good as the first one. If you don't own it, buy it ASAP. It's better than food.
