Well, their website gives us some good clues, mentioning Vienna style lager, Carared, good old melanoidin malt and hersbrucker hops added late, so we've got a good amount of information to base our recipe on.
Probably start with 75g or so melanoidin malt, 200g Munich malt and, hmmm, carared? never seen that at my LHBS, but at ~20SRM some light crystal will probably fit the bill, so lets say about 200g of light crystal and maybe 50g of cararoma for that malty nose. Steep them all as usual, then add to 9L of water in a pot and dissolve 2.8kg of light, dry malt extract and bring to a boil. Add about 40g of hersbrucker at 4%AA (should give us about 25IBU) boiled for 60 minutes. Add 10g of Hersbrucker hops 15 minutes before the end of the boil. Add another 10g of hersbrucker just as you turn off the heat at the end of the boil. Cool, top up in the fermenter to 19L and ferment with a lager yeast.
As far as a kit based recipe, I'd guess something like Cooper's Bavarian lager as a base instead of the pale extract, but I'm not really sure about getting the bitterness and hop flavor right. Omit the bittering and flavor hops and just make a little hop tea with about 15g of hersbrucker. Steep the grains as usual.
Based on the specs on their website and the specs for Vienna lagers, that shuold get you kinda close to what you are after, but admittedly, those recipes are just educated guesses. Might be a good opportunity for you to experiment and learn to tweak your recipes to hit a target. Let us know how you go.
Hmm... I might have to give this recipe a whirl myself, although I'll probably double the hops
