Around 2 dozen dining options and services (shoe shine, flowers) located on the basement/ lower level of Grand Central Terminal. A variety of mostly take-away friendly cuisines including burgers, fried chicken, bakeries, Mediterranean, French, Indian, Japanese, Chinese, Latin, soup & salad spots, ice cream & chocolates. Prices aren't cheap since it's NY, but less expensive than most of the full service restaurants in the area.
Seating areas are scattered throughout the space, and during busy hours it's difficult to find a seat. A note: during winter seasons there may be some tables and seats overtaken by unfortunate homeless individuals.
Overall reasonable place to grab a bite on the run if you're hungry and transferring through Grand Central.
