- Serve your drinks in jars for absolutely no reason.
- Coffee! Just go nuts! You need to sell at least 419 different variations of coffee.
- Overprice everything. Call it artisan, or organic, or something.
- Open your restaurant in a really shitty part of town. But state that it's "up and coming" and say something about gentrification.
I also like the suggestions about a pretentious name for your hipster restaurant. A few years ago someone opened "The Writer and The Coffee" in a strip mall on the corner of Sunset and Highland in Hollywood. It didn't last long - it hit the Los Angeles Health Department's Restaurant Closure list and ceased to exist shortly thereafter. Maybe they didn't have enough variations of coffee.
