Hi! CR is one of our faves, we eat there every trip.
Getting a table next to the tank is possible, although you may have wait, not sure of your party size b/c there are tables and chairs and rounded booths at CR and they are in rising tiers. The booth works for us-we have 2 Adults, 1 big kid and 2 little kids. We sat on the second tier on our last trip and had a nice view. DH and I have gone alone before an easily scored a tank side table. Also, if you go for early lunch when they open (11am) you may have a good chance in getting a tank side or 1st tier (lowest tier) table.
The food is good and has all kinds of things that my family likes. DH and I and DS12 tend to go for the steak and potatoes, the little boys usually get the grilled chicken and mashed potatoes (a nice change from fried food and they eat every bite). We typically go with the Chocolate Wave for dessert and the little guys have the make your sundaes (they are small, but plenty for them, especially after tasting our Chocolate Wave cakes.
I agree with a previous poster that the service is on the slow side-I don't know if it's the ambience of the restaraunt or what, but every time we eat there we have to ask for our check and wait for the transaction to be completed, but this would be our only negative for CR-just don't eat there if you are in a hurry!
