Serendipity 3 - Near the corner of 3rd Ave and E 60th in Manhattan, NY
I had The Haight-Ashbury (Sliced turkey, tomato, avocado and alfalfa sprouts with melted muenster on raisin pumpernickel with Russian dressing) and it was one of the greatest sandwiches of my life. The food was fresh and the atmosphere was great. I love their menu items, the ingredients are nothing less than fantastic. Too many places offer such limited options. However, this place isn't afraid to be bold with the flavor and they don't over-do any one thing so you can still taste everything.
