Yes, indeed, the rumors are true.  There is a restaurant serving Ethiopian food in Hillsboro.  Vikki and I had lunch there on Monday.  It's still mostly a deli/diner, so most of the menu is burger-fries and cold sandwiches, but they have 7 Ethiopian dishes on the menu, each of which comes with a salad and your choice of injera or rice.  We had a spicy beef dish, and the collard greens, both with injera.  Very tasty!  The injera was very fresh, and the flavor of both dishes was excellent.  It's a bit expensive, and portions are small, so keep that in mind.  It's not the cheapest lunch around, but a welcome addition to the local lunchtime scene for sure.
