Hi. For whatever it's worth, I'm on the East Coast -- a major city (not NYC) and can't step outside my office in the financial district and get a fresh-squeezed (real greens, vegetables, fruits) to save my life. There is no business that offers this, so I have to make my juice (or smoothie) at home before or after work. Look at what Liquiteria in NYC is doing -- this might help you. And this is what we need in my city (Boston). I can get bubble tea at many joints in Chinatown already. And the smoothies I've seen at some places (e.g. Boloco) are no more than canned fruit juice (or powder) with sugar, milk, etc. Perhaps this is what "the masses" want, but this is not what the masses need -- or the new health direction in which many people are going.
I believe website marketing for any local businesses is key. I started my business and through effective marketing and a good quality website design I was able to get $100,000 in sales in my first full year through my website. Just don't get in over your head! Signing a lease is a longterm commitment which could bite you in the rear end if things don't go as planned!
Here is an article I wrote that talks more about it and how I marketed my website to get on the front page of google; as well as, other helpful tools and tips.
Here is the link to the entire article
