I had the good fortune of looking for a place to eat in the Wall Street area and stumbled upon Mangia (in one of the Trump buildings).
It was, by far, the best lunch buffet place I have ever been in. Gourmet items on the salad bar (salmon salad, calamari, steak, etc.), including hot/cold items. This is also rounded out by serving stations with sandwiches, soup, desert, etc.
Definitely more pricey than the standard Korean deli, but worth it. Anyone else try it?
