I don’t know why everyone here has become so misrable and sarcastic! No wonder so many good people have left the Coffee Room. You should all practice AHAVAT CHINUM rather than to be known, chas ve shalom, for Sinas Chinum!
All the kosher food in Gibralter is imported, especially the meat comes from London. All the shops that are owned by Yidden (98% are owned by Yidden) are shomer shabbos and can be found on the main street.
The Kollel is an excellent one and there are many ex Gibraltarians living in London. It is worth to call the Sephardi Beth Din in London and speak to their Dayanim, whom can advise you more easily.
Much Hatzlacha in all that you do!
