We have done this x2 and love this tour. It's a wonderful tour!!
You spend about an hour at the Boma (I at first thought it was Boma the restaurant) it's a beautiful place in the middle of the savannah. You can walk on the boardwalk to see the lions, use the restrooms and eat/drink.
We are not super adventurous eaters either, but thought the food was really good. There is some tapas style selections served cold. A couple shrimp, fruit salad, prociutto, curry chicken salad (I do not really like curry, but this was amazing!) roasted pepper humus with pita rounds. We also got a smores desert. You could choose from African beers (very good!) or wines, probably both if you wanted.
It's totally worth it. The CM's are so knowledgeable, the food and drink, the special savannah tour are all very special.
