They're in the North West. Lots of different brews by them. I've had a few: Irish Kells, Dead Guy Ale, Yellowsnow, Half-e-weizen, Chocolate Stout. Out of that lot the Kells and Dead Guy are my favourites. I'm lukewarm on Yellowsnow. Didn't care for Chocolate Stout (not a stout fan) and hated the Half-e-weizen (don't like Belgian Wit beers, stupid corriander, bleah!)
I should hopefully be getting my hands on HazelNut Brown Nectar later this year.
Otherwise I suggest a look through ratebeer.com.
