A friend and I are doing a 'food marathon'- hitting 4-5 places in Manhattan on a Friday in October (figure 10am-4pm). Don't worry, we're professionals and we've done this before in other cities.
We're thinking Grimaldi's for pizza (and I don't want to start a 'best pizza battle,' so don't waste your type). We'd like a solid Chinatown choice, a gourmet burger place, possibly Indian and perhaps something else (maybe deli, maybe a hot dog).
Keeping travel strategy in mind would be helpful as well, so it's a geographically logical expedition.
