Heading to Beijing

[alexzabr]

My wife will be flying to Bejing for work, chances I'll join her also. We'll be staying there for about a week in a hotel.
Well, this time most ceraitnly my thinkpad will be left home (less things to worry about), bearing my avid photo amateur habits I'll rather be taking my SLR gear with me instead (a Canon body with 2 lenses + film...) to enjoy and shoot the city.
My wife will be at work during daytime and at evening will be spent together exploring the evening city, enjoy restaurant meals, etc...
During daytime I intend to take a strolls along shooting around, probably also one or two city tours.
This is our first time there (albeit I used to fly to Honk Kong, Taiwan in far past for work as well) so I'll eager for your recommendations of places to visit during daytime hours, evenings to enjoy evening city or nearby environment, a good (not necesserily overly expensive though...) seafood restaurants. We both are seafood fans, especially the fresh kind available in Asia countries (the kind of resaturants where there is huge aquarium filled with various kinds of life creatures, so you just point to the one that you seem to like to be eaten and they will prepare it right away. I was in such place in Taiwan 5-6 years ago - the most joyable seafood eating experience I tried ever, now must have my wife to enjoy it as well).
Usually, such kind of restaurant are away from most turist-crowded places..

So guys, your advises on photogenic daytime and evening places are most welcomed as well as regarding the meals.

Also, is Bejing a secure place to wonder around with exposed camera gear ? Of course, there must be places that aren't particularily advisable to get in with anything expensive (as in any other country), but in general ?

Thanks in advance, Alex
