Well, in FR Coffee is from Maztica and sells for ALOT. I guess what would be a basic thing I'm looking for is perhaps a "return on investment" number on a business like this.
I think the coffee house will be a huge hit in Waterdeep. She's building it in a very nice, ritzy, part of the city... in a corner location, near everything pretty much (Sea Ward, you don't want to know how much that cost her). Keep in mind the city size is between 125,000 in winter and as high as 300,000 in summer. So, she should make a ton of money. What should the basic "return on investment" be? I think for an idea like this, the first year or two should be massive... and it'll go down as competitors set up. So most of the money will be made up-front I suspect (unless she can keep competitiors from opening their own coffee shops, but in a city like Waterdeep, that's unlikely).
