Gotham West Market
Hell's Kitchen
Gotham West Market is a food hall that works well for a first date because it isn't too large or bustling but still has a ton of seating and a nice atmosphere. Gotham West (and food halls in general) let you do dinner without comitting to "doing dinner" on a first date. Regardless of what you eat, get Ample Hills at the end.

Eat
Ramen, Jianbing (Shanghainese crepe), Pizza, Seafood and Ample Hills icecream are all at your fingertips.
