I generally avoid "Bourbon St" as it is noisy and busy, too much for a wedding. Recently I was surprised to find a place that the management does an excellent job in accommodating a small wedding party right off the busy street. " Bourbon Heat has a nice courtyard and upstairs area it can use for small weddings. The manager there goes out of his way to assist in making a unique wedding in a historic spot. Contact them to be married on one of the most famous streets in the USA.
