We walked from the Hard Rock back to the pier, window shopping all the way..Like all the HCC-its noisy, overcrowded and overpriced. Guess its my age!! There was nothing I liked about it, and it was on the second floor with no AC on in June, just ceiling fans. It is smaller than the one in Banff(i think that one is out of business) and smaller than the one in Niagara Falls.. But, if you like it, go for it. You will probably have a better time at Carlos and Charlies!!
We just bought our souvenirs there, but didn't eat there. We collect t-shirts and guitar pins. We ate at Panchos Backyard at an authenic Mexican restaurant. I would recommend this place. It's behind (connected to) a store called Los Cinco Soles. Our cruise port consultant said they have "guacamole to die for " and she was right. We had chips and guac. and then a meal. I think it was cheaper than what the HRC would have been too.
It's right in town, Dan is correct, only 10-15 minutes. Cab fare a few years ago was $5 per car from the Carnival dock, probably not much more now. It is very small and the food prices weren't as cheap as the other restaurants. When I was there, it was dead.
If you happen to be going to Grand Cayman also, there is one there, much bigger, good food, pricey since C.I. $ is worth more than US $. From the dock, probably $8-10 C.I. to get there.
It's not too far, but I can't tell you whether you could walk it or not. It's a 2-lane road, and the drivers are kinda crazy, besides driving on the wrong side of the road from what I'm used to, so I'd probably catch a cab. The guys at the pier could tell you for sure the distance.
If there's something special you're looking for, email them in advance and they will hold it for you - the manager, Paul Pearson, held a jacket for my husband for a month til we got there. Good thing I emailed him, it was the last one they had. My husband wanted it from there, since you don't see a lot of Hard Rock Cayman Islands stuff, mostly New York, LA, London, etc...
Have fun, spend some time on the beach, it's BEAUTIFUL!! The sand is so cool (it's like teeny, teeny, tiny shells and bits of shells).
Hard Rock Cafe in Grand Cayman is less than a 5-minute walk from the tender pier. You can see it off to your right as you leave the pier. Prices are in GC dollars, which are more valuable than US bucks.
