Last month I visited Black Pearl in Koramangala and I must say I was surprised with their ambiance(Pirate based setup) we had an awesome birthday party of one of my buddy with the cake cutting and singing songs.
They also have a gentleman who sings very good English songs and we requested him to sing one of our favourite song and he did sing with no hesitation.
I would rate out of 10,
Taste- 8
Ambience- 10(Full value as the gentleman sang for us)
Value for money- 9
Staffing- 10
