Sanaa after dark, so your girls won't even be able to see the animals out the window, probably won't work for a 3 and 6 year. It is definately more of an adult dining palatte menu.
BOG has very good lunch food. I recommend the Braised Pork, they call it Slow-Cooked Pork on the kids menu. It tastes the same as pot roast. The kids grilled shrimp on the kids menu is also good, if your 6 year old eats shrimp. I love the chocolate cream puff myself, but everyone needs to try the Master's Cupcake once--maybe the girls can split it. Tastes like cookies and cream jello fluff. (Warning, don't try to unwrap it, no on can, and you will just destroy it in the process. Eat it out of the wrapper, or run your knife around the edge to get it out.)
For girls that age, go with BOG.
I don't understand your "Disney expert friends" reference to wait time. Perhaps they haven't been since it went to reservation only? So they are referring to standing on the bridge in the sun, waiting for a walk-in? Sounds like questionable "Disney experts".
Thank you so much! I love the perspective and the advice from real experts. Disboards is the best!
