Anything can be a viable idea. You just need to do the research. Talk to your gallery customers. See if that is a service they would be interested in. You may find that they would like more than just a cup of coffee --- maybe a cappuccino or espresso or even a cup of hot tea.

Ask yourself what your basis for adding this service to your gallery is. Is it to keep your visitors there longer? Is it to add another revenue stream to your gallery?

Talk to your local SBDC, they can definitely help!

Good Luck!
