I'm also planning a Coffee House/Cafe.
I, too, have no floor plans.
Right now I'm going from shop to shop looking at what they have done and making mental notes of what I like

and what I hate :evil: .
Trial and error works if you have an unlimited bank account....I do not have that bank account so here I am new to your forum.
I am trying to learn from the "big boys" and indi's who have successful shops already open.
*$'s sells coffee and seem to stay open (so far). So perhaps you should study their layouts. I'll bet that business schools all over the world are looking at them.
Don't look at the "Wall Street Successes" only............ Big money fails as often as the small shops. Small shops can use "sweat equity" and the big corp.'s can provide an economy of scale volume. Use what you have and learn from what "the others" are using and doing.
I am hoping to get a feel in my shop that would scare off executives for & investors in McD's and W-mart.............of course, things could change and I might see the day that McD's and W-mart are places I would want to hang out in. Personally, I am not waiting for that day.
So who has those floor plans?
