Do you need experience to open a coffee bar?
I read with interest many of the posting about this question. Sure, its nice to have experience but if everyone had experience in the type of work they wanted to do everyone would be an expert. My husband and I got into the specialty coffee business five years ago - without any experience and only the love of great coffee and a desire to be on our own. We did alot of homework over a couple of years before we develed into investing any money. Neither of us worked in espresso before! The key to making good espresso was learning from experienced people (not baristas but coffee people - roasters!). They are the ones best to learn from because they know what their product requires. Don't rely on hiring trained staff. It is too difficult to retrain them and too easy for them to do it their way. Who's to say they are making it right, except for themselves?
Check your local area for specialty coffee roasters. Interview them as if they were coming to work for you. Critique their product and customer service. Talk with other shops that may use their products and make certain you inquire about their customer service. Are the roasters just looking to get their product sold or are they interested in helping you become successful? They may also be a resource for equipment they might lend you while you purchase their product. This probably won't apply to an espresso machine (too costly). Seriously look at a 220v! They are worth the money and with proper maintenance can last a very long time. We've used a number of machines, Pasquini, Caramali, Futuramat and lastely an Iberital. I'd have to say my favorite was the Caramali but too costly to maintain. Second choice would be the Iberital.
As far as your building, if it is mobile, check with your local health department for mobile vending unit codes. Most counties and states east of the Rockies don't have a clue what an espresso kiosk or drive-thru is and may, at first blush, tell you you simply can't do it. We have manufactured units that have gone as far east as Wisconsin (we have the first with an ADA approved bathroom). You may need someone to interpret your local codes for you.
The best advice would be to do your homework in depth before you start investing any serious money and pursue your dream! :grin:
