a-ron -- you might get more of a response if you post this on The Inside Scoop, or ask specifically about schools on the Culinary Students board.
When you do that, can you be a little more specific with your question? When you say "coffee house" do you mean a place that serves coffee and other beverages, and food? Or a coffee roaster, that processes and sells beans retail and wholesale?
Some advice, though: learn all you can about running a business, in general. The problem many people make when they open a restaurant is that they don't view it as a business like any other, where the most important thing is to MAKE A PROFIT and STAY IN BUSINESS. That requires math and language skills, science, history -- all the subjects that you should be learning in school. The food and beverage part is important, of course, but if you don't know how to run a business you won't stay open very long.
Hope this helps.
