Note: I think the name of this restaurant is actually "Merkato" and has moved from the Twain location. I also posted the following review for the twain location.
As of December 26, 2016, this restaurant has RE-OPENED on Arville 1/2 block south of the Orleans Hotel and it is excellent. Delicious and plentiful food, very friendly staff, better location, and the food is more interesting and varied than what I have had at many other Ethiopian restaurants. We got the vegetarian and meat sampler platters and it was more than a very hungry family of 4 could scarf down. Under $30 for all of us, a great price performer. Take a short walk from the casino and enjoy some fresh air and some delicious Ethiopian food, where (unlike the buffet) you are encouraged to eat with your hands.
