Definitely worth a try! I was a little askance at the location, but when we sat down we enjoyed the chill atmosphere and privacy.
We went for my roommate's birthday, and upon learning it was her birthday the owner's (who are also the major servers/hosts) treated she and to beers on the house.
The food was fantastic and a great experience as it was my first time trying Ethiopian. The Doro Wat comes very spicy, warning to the weak of tongue. The chicken special combo was a great buy and could have fed three people.
If you go for hookah, that can smoked in the bar which is separated to the side of the restaurant. If you are looking for a party spot, this isn't for you. They were not very populated, but my group preferred that aspect.
The only reasons that I have for taking away stars are:
* the sketchy location (though it's not unsafe, just in a weird spot)
* the hours for the restaurant are 11 am-10pm, and not 11-2 am as listed on the site
* the owners are obviously not native English speakers, and were slightly awkward at first
* The food does take a while to get to the table
Otherwise, the Groupons are great buys and you get your money's worth even without one.
