Yelp - my best friend in New York City after Trader Joe's :)

After Trader Joe's, Yelp is my best friend in New York City lol It was recommended by a friend as soon as we arrived in the city and our relationship gets stronger everyday lol
I do not do anything without asking for its advice...It is an essential tool to have in a city which offers so much as New York does :-) Mainly for newcomers who do not have a clue about restaurants, hairdressers, flowers, eyebrow threading, waxing, real estate, professional services, hotels and travel, etc....Whatever you are looking for, I am sure you can find useful reviews there :D
