The Chelsea Market is filled with great restaurants and speciality food stores and pop up shops. I love stopping in and getting a gourmet grilled cheese from Lucy's Whey or a healthy juice from raw food restaurant One Lucky Duck, while shopping for dinner ingredients at the Italian market Buon Italia. For a great sit down restaurant, I love The Green Table, which serves great farm to table food.
Its quite a trip out there but so very worth it if you wanna have the very special beach-experience! You can go there by car and then take the ferry either to Pines or Cherry Grove (I would prefer Pines!) or you do all by public transportation - there a "getaway tickes" for 36Dollars and the transfer works really smooth - may even be faster than by car!
It's Christmas year-round at Panna II, as the walls and ceilings are completely covered with festive string lights. A great restaurant for a group dinner, Panna II offers small sharable plates in a fun and lively atmosphere. It's BYOB with no corkage fee so stop by the liquor store beforehand to pick up all the wine, beer and liquor you can carry.
