So I have a favorite Ethiopian restaurant back home that I compare every other Ethiopian restaurant to. Abyssinia is the equal to it, if not even better.
May I suggest the combo platter. They have both a vegetarian version and one for the carnivore. It was more than enough food for the four of us in our little group.
Be forewarned that if you've never had Ethiopian food before there are two things to know. 1- you eat with your hands using injera bread. It's messy but tasty. 2-if you are a spice wimp this might not be the food for you. My daughter still loved it but went through a few glasses of water.
You won't go wrong eating at Abyssinia.
