Of the three TS restaurants - Jiko, Boma, and Sanaa - only Sanaa, in Kidani Village, has windows overlooking the savannah so you can watch the critters while you eat. The other two don't have overlook windows, but it's easy enough before or after your meal to see animals from any one of several viewing points. As far as restaurant choices, we really like Boma for the variety. The animals are out at all hours.
The safaris offered at AKL are another matter entirely.
We didn't eat at Sanaa on our recent visit - the menu sort of freaked the rest of my family out (wimps!) - but the view couldn't be beat.
