I've never eaten at Tusker but I have eaten Boma's for breakfast (just last week) and it was fantastic!! There were a lot of breakfast items offered: oatmeal/porridge, cereals, fresh fruit, scrambled eggs, omelets, potatoes (delicious), bacon, sausage, fresh pastries, carved ham, jungle juice (yummy), etc. We sampled a big variety and the food tasted fresh and delicious! It only takes 5 minutes to travel from AKL to AK however you should factor in a 10 minute wait for the bus, just to be safe. On the other hand, the advantage of eating at the Tusker House is that you are in the park already (an advantage if you are planning to eat and get done before rope drop) and also there are characters.
