I love Ethiopian food, and Abay is a great example. The food is delicious and the meal experience is fun and social. The restaurant is also vegetarian friendly (and in fact the best stuff seems to be veggie).
My wife and I ordered a veggie combo: messer wat, shiro wat, kik alicha, and one of the gomen dishes (the one with cheese). We loved all of the different dishes plus the samples of others they brought to fill out the platter. I will particularly compliment the shiro wat and the kik alicha (garlicky and not too mushy--perfect!). I also thought their injera was flavorful and had just the right bit of acidity. At $22, the veggie combo is a great deal for two people. The meat combo is a bit more expensive.
We had the chocolate cake for dessert and loved it too.
The only disappointment is that Abay is BYOB and yet charges a corkage fee. In my mind this is wrong. Also, it's a crime not to serve honey wine. I really look forward to that when I go to an Ethiopian restaurant.
