I like Frankie's and it is certainly unique in terms of decor. I'll go back, but it really isn't all that unless you like to drink exotic specialty rum drinks. If you like them you will have a field day. If you don't, it's really not all that extraordinary.
The music and the retro footage on the TV are cool, but it's not enough to really grab my attention for an extended period of time.
Though it would seem to be very cool and eclectic, it actually feels kind of sterile to me once you settle in and know what to expect.
Mos def experience it and see for yourself, there's nothing wrong with the place.
