YES. The food was incredible. We had the vegan tasting menu and it was truly delicious. I loved all of the appetizers and the mains, but the eggplant appetizer and the greens in the main were especially amazing. The injera was fluffy and sour, the way it should be. I also tried one of the micro-brewed beers on the menu and it was great. The only reason this is a 4 instead of a 5 star review is that, given the ingredients used (lentils, split peas, veggies), it is quite pricey. $30 per person before tax/tip/drinks is a lot when every other Ethiopian restaurant I've been to (and I've tried many!) has charged around $10-$15 while serving a similar amount of food. It's true that the quality at Nil Bleu is top notch, as was the service and ambiance, but it's hard to want to pay double what you would elsewhere for very similar food.
Edit: Forgot to mention that none of the dishes were spicy, which for some people might be important for Ethiopian food. I still thought they were all delicious, but the person I was with was disappointed.
