I know, you probably already googled it... but on our last trip we did go to Fryer’s Delight, which is the "Cabbie's Choice" for fish and chips (when we used to live in Manhattan, we used to go to a restaurant on the Upper West Side that was "cabbie's choice"... brilliant food... hence the willingness to give it a try).
We weren't disappointed.
