Where you put a Korean anything, you better have a great number of Korean residents near by. By making any place (food, drink, healthy or not establishment) a named Ethnicity you close off others so for the sake of your success keep it open in that regard. Piano? hey I take everything with a grain of salt and ask how many hours of radio and TV is dedicated to piano? What is generically popular might be after school hours of customers liking hip hop or indy music, the during dinner through to after dinner crowd might like classical music and early morning workers classic rock. Noon time piano so you can keep your fingers loose might be perfect. But the ambiance isn t what s up. What you are offering on some sort of menu is what will bring in the millions. Smoothie got my attention I think when it all comes out in medical journals the the human body needs two cups of fruit and two cups of vegetables a day and some kind of meat a smoothie and sandwich shop would kill. for lunch hours have a 50/50 half a sandwich and half a smoothie, Korean coffee no problem sell it s health benefits to the local community. Your name could be the shops name like Sylvie s Health Stop Or Nancy s Healthy Ways but a must would be peanut butter and oatmeal cookies, blueberry and poppy seed muffins, coffee and tea, sandwiches with sprouts not lettuce, turkey bacon, sliced chicken, turkey, beef, tomatoes, avocado s, onion, cucumber, and only specialty cheeses, like, provolone and muenster and swiss, only natural multi grain breads, no soda, no unsweetened, no fatty fried foods or fried chips, just what every body needs and priced to be competitive with subway s sale prices. (oh! you will need a fairly large parking lot in So Cal and if you can get close to a theater complex all the more better because people will stop on the way in to the theater to take your stuff in with them and you can offer a 10% discount with movie ticket stub in hand for all those coming out. Good Luck and let me know where you end up doing this.
you better do a LOT of research to see if there are ANY successful businesses like that ANYWHERE and if there are what exactly are they doing to be successful - you would need a very high foot traffic area, probably especially in the evening and NEAR a movie theatre if you expect to get after movie people - that would be very expensive to rent - probably an urban downtown location where the neighborhood doesn t shut down at 6pm ( I have seen downtown areas that DO shut down at 6pm)
