I met the gentlemen in the video. About two years ago we took this sort of offbeat tour of Budapest's District VIII. District VIII is and has been sort of the lower end of the social spectrum ................ and a melting pot of Roma, Jews and Hungarians. A fascinating district. The last stop on the tour was a Shul at Teleki ter. The shul wasn't much more than a modest couple of rooms in the back of an apartment block that had been used as a prayer room for at least 50 years prior to WWII, then entombed until the retreat of the Soviet Occupation Forces. The odd thing was, with all of the Jewish presence in Budapest, we found ourselves drawn back on a few occasions. These are good people doing good things. If you find yourself in Budapest this community and all the Jewish communities could use your help. It's good to give back when you travel.
Maybe @worldinbetween has some other suggestions,
