I went to Sheba earlier this year and whatever I got was just typical Ethiopian, but you simply must go for the coffee.
Typically in coffee shops you have a choice of countries and Ethiopia is always represented, so why not go directly to the source (in terms of Toronto)? Sheba offers an amazing coffee ceremony (yes, ceremony!) that takes a while but is sooooooooo worth it.
It's served with popcorn which is bizarre but, hey, you are going for the experience!
PS Get the injera, it is delish.
