Tour start/end point?

Hi. I’m a travel writer starting tours in the borough (currently I’m focusing around the Hackney Central area with routes incorporating Stoke Newington, Dalston and Hackney Wick. I wonder if anyone would be interested in collaborating? This would just mean maybe using your cafe as a start or end point? Maybe you’d offer a discount and host some posters? My clients would have somewhere to wait and you’d get some extra custom. Maybe there’s something quirky/different/historical about your cafe. But – you must do good coffee! It’s still evolving, but let me know and maybe we can help each other out. Best,Simon
