We usually eat at Yak & Yeti, sometimes Rainforest Cafe, we have infrequently eaten at Tusker House.
If we are doing an a la carte sit down Yak & Yeti is our first choice for TS at Animal Kingdom. If you are looking for a buffet, then TH is your go to choice for AK theme park.
The Satu'li Canteen is pretty decent for QS, we ate there and thought it was pretty good for fast food.
If you want a more upscale dining experience as an alternative to TH, there is Tiffins, or Sanaa (at Kidani Village/AK resort). But you are already doing Jiko for dinner.
