Fancy coffee in little cups can go with the trendies and Rapha kit in some remote city. that might fit in with a themed café but who the hell would want one. Thats not a cyclists café. Who the hell wants to pay to go somewhere like that?
Maybe, but if I was running a business I'd be very happy to have one more like the Rapha cafe than some of the typical club-run cafes : )
If you're going to have a bike cafe, make it a nice one with interesting stuff and good food. Take the Rapha clothing and name out of the Rapha cafe (sorry, cycle club) and that's all it is, it just does the basics and the details well.
If I want good food and coffee there's loads of choice and it really makes little odds if it's a bike cafe, just a nice or convenient location and a suitable spot for the bikes. Cake and tea/coffee is the basics but it's not what I'd go for, CBA with long mid-ride stops but it's good to end a ride at a cafe and have proper food. ie food you can charge more for, a full meal. Doesn't need to be a wide range, just good post-ride stuff. Maybe watch the TDF in the evening with your partner while having dinner (romantic no, fair compromise for many with July syndrome yes..)
It's attracting a regular crowd more than once a Sunday that's important and that will vary by area.
Edit, just thought of Pete's Eats in Llanberis. Bunk-house upstairs for weekend trips. That's a winner if the local riding is worth traveling for, if you could book a 6-bed bunk room and have a bike cafe for breakfast and dinner. Or use it as a stop-over for a long weekend ride.
