My husband & I will be staying @ Hotel 17 (on 17th between 2nd & 3rd). We are foodies on a tight budget. We'll be exploring in Greenwich Village, Chelsea, & the East Village. Sharing a pastrami sandwich @ Katz's is on our must-have list. What are some restaurants we can enjoy a good, casual dinner (& a drink) @ but won't break the bank? How about places open after midnite? Thanks.
