Blue Nile Cafe is located in a little strip mall and the prices are pretty reasonable. This is definitely a great spot for vegetarians or anyone that likes Ethiopian food.
I usually alternate between two dishes when I eat there- I've had the Suro Watt, which is chickpeas in some kind of sauce (really good) and Begerdan, eggplant with bell peppers. I recommend them both.
If you've never had Ethiopian food, don't be afraid to try something new, you'll be glad you did.
