I think concierge in India is just a glorified bell-desk captain.
I would love to be proved wrong and you are invited to tell it is otherwise but in most hotels (and I am only talking 5 star + here) the concierge just wouldn't know where the closest art house is, let alone having visited one himself.
here is film for inspiration.
All General Managers / Front Office Managers make sure your concierge works to present something similar and in the bargain you will find he/she has improved their communication, presentation skills, knowledge and customer service attitude.
p.s. please make sure you let them take the time required to make something like this.
