Hi Satyam.
I can make you a website like that one, within 12 hours from now.
I know how it works. When you type in a letter, it calls google maps API for a location, and lists all of them in the dropdown. Once you select a location, it displays the map for you and the first most relevant bar where you can go for drinks.
Please let me know when can I start it.
I will do it for $800 and 60% advance payment is required.
Thanks,
Rohan.
