For quite some time, I've been on a quest to find authentic British-style fish n' chips. And by authentic I mean with a thick, yet light tempura-like batter, often battered in beer. I've had Matt Murphy's and while I like the whole "wrapped-in-newspaper" touch I don't feel like the fish 'n chips are that exceptional (or authentic, like the real fish-n'-chips shops you'll find when walking down the street in London or Dublin, for example.)
Found something pretty close to the real thing, and of course it was in Dorchester--the Banshee. A real Irish-pub, filled with tons of Irish staff and patrons. We went on the later side on a Friday night, ordered a plate of fish n'chips and one of shephards pie. Both delicious; fish had that tempura-like batter (i think it was beer battered) and chips hot and salty...mmmm.
Shephards pie was excellent too, made with ground beef (vs lamb)--perfect comfort food.
AND --the next best thing to having found these delicious fish n' chips was having discovered a new delicious beer I never knew existed --Sierra Nevada Brown Ale. Served right from the tap in a proper pint glass, went down smoothly with those sublime fish n'chips.
