The CG is one our ALL TIME favorite places to eat. We (dh, me, my parents and 2 DD's) ate there in 2006 when the girls were 3 and 5, and we just got back from Disney yesterday and ate at the CG AGAIN!
Early ressies are KEY if you ask me, we had 5:30pm ressies both times so we didn't wait until the girls were cranky from hunger. The waiter, Ryan was a DOLL, he has worked there almost 9 years and really kept dinner moving. The girls got menus and crayons to color on and that kept them busy for a little while, then they made a few trips to the bathroom...that is always of interest to them for some reason
I'd say dinner was at most 90 minutes long, definately NOT 2 hours...everything moved along fairly fast, and we even had appitizers. We were on the dining plan so cost wasn't a huge issue, but out of pocket it would have cost us over $200 for the 6 of us.
Again, I am sure our waiter had alot to do with how smoothly and quickly dinner went. Sure, CG is upscale but there were lots of families with young kids there so I wouldn't pass up CG for fear that your baby may cry.
And even though tables are close you can certainly walk to the front area where the elevators and bathrooms are located and try to calm a crying baby there. The food is truely amazing!!
