do they slice lox by hand any more in Brooklyn??
or do you have to schlep to russ daughters on the LES??
Fairway & Garden of Eden, for starters. Last time I noticed, G of E had lox in addition to several smoked salmons. Didn't notice if Fairway has lox but they certainly have a very good assortment of sm. salmon. Surprisingly, it was quite expertly sliced at G of E (expert slicing is no surprise at Fairway).
If by "lox" you mean Smoked Salmon, FAIRWAY has a good selection, and you can taste before buying. They also have Gravlax. They will slice paper thin if requested. Serves with a homemade Mustard Sauce, it makes a refreshing starter or Summer salad
Ditto for Garden of Eden, but I don't think they sell as much as FAIRWAY , so not as fresh.
