Why was は removed from this sentence?


So here is the sentence:

[code]

    このスプーンすてきですね
    
[/code]

Why didn't we say:

[code]

    このスプーンはすてきですね
    
[/code]

Isn't スプーン the topic of the sentence? Why did we remove it? Why did we leave
it in a sentence like:

[code]

    とうきょうはきれいです
    
[/code]




Particles, especially は and を, are often omitted in colloquial Japanese.
Formal Japanese would require the は to mark the topic, as you suggested.
Compare

> ご飯食べる?
