Definitely worth a visit. A unique experience. If I remember correctly there is a cafe near the glassed area on the ground floor, it was really nice sitting in the morning sunshine and relaxing. We visited in 2017 so I hope the cafe is still there.
This video is 5 years old - Bruces' house has long since been demolished, sadly. Some parties wanted to keep it as a type of museum, highlighting his legacy, but they couldn't get sufficient funding to do so. A pretty vile thing to do, given how Bruce made Asians everywhere feel like they were human and important again, after many years of being put down and ridiculed !
God knows lol. But they are using less phones now. Back in the days they needed to use multiple phones which means multiple network between drivers to get more orders. Now they use apps which are more efficient to get good orders
