This was the first time I had Ethiopian food and wow, so delicious. Their lamb dish was superb! Since I was a newbie, I let the server decide on my two side dishes and I wasn't disappointed. Cabbage and carrots, and corn. Both were delicious and their house Chardonnay was not bad at all.
Our server was attentive. I agree that it's not much on atmosphere there, but I was with friends and that wasn't all that important to us, since we were enjoying good food and each others' company.
I will definitely go back, and consider Tana one of my new favorite restaurants.
