As would be expected, Shizuo's snowglobe will contain images from the city that he lives in, Ikebukuro. Since he spends a lot of the time in the city in general, it will likely cycle through a number of different popular spots in that area. Here are some screenshots to give you an idea of what it looks like.
The last image is Russia Sushi, a sushi restaurant owned by a friend of Shizuo's. He goes there often.
There is also this pretty cool
comparison post that shows you the Ikebukuro in the anime vs. the Ikebukuro in reality.
Let me know if you have any questions!
