we've enjoyed both the mentioned (WPC & RR), as well as cap'n jacks. haven't tried planet hollywood only b/c it tends to get a
lot of "less than favorable" reviews (including by our friends & family).
of the three tho, i really can't say one is significantly better.
~ raglan road: outstanding entertainment (will prob go back & sit at the bar, just to enjoy it again). we've seen the band with an irish dancer, as well as a solo singer ~ both were excellent! however, food was just so-so

. a number of reports of very slow service (we have not experienced that tho).
~ wolfgang puck ~ food was outstanding, as well as creatively prepared & presented, but restaurant can be very noisy. again, a number of reports, but not experienced by us, of snobby and/or rude waistaff
~ cap'n jacks ~ nice atmosphere, quieter than the others, can get twin lobster tails on
DDP
we could prob be of better assistance if we knew the composition of your group, food preferences, etc, but hopefully, this gives you a general idea (also, check the menus for each restaurant for help).
