I've these thoughts about quitting the computer industry altogether and starting a "normal" business either a coffee shop, or a sushi bar.
I would like to make my own "real" coffee creations, like, buy whole beans, roast them on my own and brew them to really good coffee :)
What would I need for a small (average starbucks-shop size) coffee shop in terms of equipment?
I hope we can gather some tips together :)
This has been answered well on "What does it take to open a boutique coffee shop " on Quora.
Googling for "how to start a coffee shop " and "coffee shop business plan " yields plenty of resources too.
You'll also find the National Coffee Association helpful for research.
I'd think long and hard about the hours involved in starting a coffee shop. I had a friend who did it in Cali and she was sleeping about 4 hours a night. People want coffee when they wake up. That means you have to be ready to go at 6 a.m. or so... I just bring that up because I think a lot of programmers are nightowls who really value flexible hours, but I'm sure that's a gross stereotype.
