Hm,
Mirror's Edge. A very clean, neat style that still looks "realistic". I prefer it over Portal's minimalism. The bit in the large stormdrain was fantastic.
Deus Ex: HR: Again a very good looking and consistent art style. Some people complained about the overuse of yellow, but that was never an issue for me.
Honourable mentions go to Civilization IV and V. Although they aren't "beautiful" in the way FPSes usually are, they have a very clean and easy-to-read look with a very nice user interface.
