This new sandwich shop is moving into the north side of the old Sonic Boom location (next door to Mooberry) and plans to open in Spring 2009.As the sign in the window says: Homegrown is built on the principal that Seattleites who live the organic lifestyle at home shouldn’t have to sacrifice their ideals when they’re eating out for breakfast, lunch or appetizers after work. I’m all for this approach, though I’m wary when politics are put before taste. There’s a mission statement posted; I want a menu.
