This is basically THE Jewish bookstore + Judaica shop in London if you're not on the Orthodox spectrum (plenty of shops cater to MO & Haredim across N London). It's part of the Reform Movement's campus and has a somewhat mindboggling collection of new and second-hand books crammed into a teeny footprint. You'll find everything from that second-third-fourth-hand Joan Nathan cookbook (complete with stains) to a brand new cling-wrapped Chumash hot off the press somewhere in the US. You'll also find just about anything else you may need, from a kiddush cup to a tallit, across the spectrum of price & quality.
The owner is a little gruff but knows his stuff (ayy rhyming) and will help you find something if you're lost, or order something if it's not in stock.
A bit out of the way but totally worth a visit if you're near GG. read more
