I hate to be the Negative Nancy here, but tank side tables are not always the best. On our last visit (we wont be going back to CR anytime soon), my girlfriend and I had a table right next to the tank. It was fun for a while, but we had constant intruders on our meal. Constantly there were kids standing over us to look at the tank and not many parents did anything to stop them. Having kids yelling back to their parents or just in general, in your ear, while your trying to enjoy the meal really put a damper on things. If you don't get a table next to the tank, don't think you are missing out on anything special.
