I was pleasantly surprised last September. We stayed at the CBR and Shutters didn't look all that exciting, but we went one night and it was fabulous! The service was beyond excellent and the food was some of the best of that trip. Unfortunately, I think it was the one meal I didn't take photos of, because I wasn't expecting to like it. But, IMO, it was well worth it.
we are actually staying at CBR this September and we were discussing the same thing, its okay if you want some food lol. It definetly wasn't the bestttt restaurant, but if you want to stop by for food one night it is suprisingly good its a nice dinner to go to if you are at CBR, but I wouldn't travel distances just to go there.
