it needs to be associated with internet cafe businessThere are many ways in which you can research for your cybercafe logo design.
One way is to look at what others have done before (links open up a new window):

There are different things that you can emphasize in your logo design.
For one, you should think about the core business of your cafe.
If you have a gaming cafe, for example, I've seen many very successful cafes use logos that resemble logo's on many popular PC and console game designs, which makes sense in many levels.
If your cafe is primarily a cafe and the internet terminals is just a side business, you could think about looking at what type of logos successful cafes use in their logo designs.
For those who use outside logo designers, it makes sense to go with companies that have done successfully logo designs for companies before.
If you find a logo at a successful internet cafe, most such owners don't mind telling the name of the company that did the logo design, and you may choose to use the same company.
You should also think about the environment in which the logo will be displayed, especially offline.
If you want walk-in traffic to your store, your logo should be noticeable from its surroundings and encourage people to take the step of walking in to use your services.
