Peter Doyle @ The Quay (Doyles fish restaurant)

Here is an example of a perfectly designed logo.

1. It is simple. Anybody could draw it and/or recognise it.

2. The type is perfectly suited to what it sells. A fish restaurant with 2 fish as the logo.

3. It is catchy (no pun intended). After seeing it, you realise that you could have come up with the idea, but didn't. Even if they had a hundred different designs, you would look at this one and say "Enough. This is the one"

Great work, Peter Doyle. Perhaps I will have to come and try your food someday.
