Well, I've had it once. But looking on the website gives some clues.
Dundee Pale Ale
A wonderfully balanced true pale ale. Cascade, Tomahawk, and Amarillo hops create a citrusy aroma with a smooth, crisp finish. A subdued malt character nicely complements the hop complexity and produces an orangey amber hue.
ABV: 5.3%
IBUs: 35
So if I was to make it, my first try would be something like this...
