I will mention that the character interactions at Tusker House were outstanding, when my husband and I were there in July.  Mickey, Minnie, Donald, Daisy, and Goofy.  As far as the food goes, it seemed to me that your options at Tusker House are a bit less adventurous than at Boma.  I would give a slight edge on quality to Boma--not sure whether that is really true, or just my perception.  Service was outstanding at Tusker House, and fine at Boma. 
If you are uninterested in the characters, then I would suggest Yak & Yeti.  This can be a hard reservation to get, I have heard, but it offers a nice range of choices.  At others have already commented, Tiffins is a signature restaurant, with all that entails.
The bowls at Satuli Canteen are quite nice, and I think that you can build your own.  So that offers good options.
