I'll bet just about all of us know a bike-themed restaurant/bar/coffee shop that didn't make it, just as the thread states. I always sort of worried that the better a shop was at attracting riders, the worse the profit potential might be... because the guys I know (you know who you are) hanging out at the Second Cup at Parkwood, for example, stay a long time, but don't buy much. No better money to be made from me, though, as in spite of being a regular customer (yes, to the point of monotony) at the donut shop at Princess Auto - what keeps me coming back is I can get my lunch there for less than $3, which doesn't leave much margin. There is a place on Commercial in Vancouver that does attract a fair number of Italian bikes on summer evenings, and a few years back, the very, very, tiny White Spot off Robson filled the full block in front with motorcycles on any decent afternoon or evening... I don't know if that state of affairs is still going on.
If the coffee costs enough, maybe a place like that could operate here - during what passes for the season. But then winter comes... an alternate plan attracting different customers, or keeping the same ones coming, would have to be in effect.
It's a pleasant idea, and in some rarefied ecosystems, like Los Angeles, where the Candy Store and The Rock Store attract hundreds of bikes on weekday afternoons, I'm sure there is some (sufficient) money to be made in catering to this clientele.
