I have to chuckle a little on the soda comment, only because I have never rated a restaurant based on their selection of sodas. It's all about the food. The drink selection is NOT why they are in business.
With that being said - I had their water the day I was in there and it was very cold. Of course, I went in there at around 9:15 and had the water that was in the back of the cooler, so clearly it had longer to chill.
