I am visiting NY in a couple weeks and going to see Fuerzabruta on a Sunday night. The show starts at 7 pm so I am looking for a place for early dinner at around 5 pm. The theater is at 101 E. 15th St. (b/t Union Square East and Irving Place). Is Momofuku within walking distance? We have an 11-yr-old so somewhere not too formal will be ideal. We are open to any type of food, any budget. Thanks.
