The notable Chef Masaharu Morimoto, of Iron Chef fame, is behind Momosan, which is intended to showcase ramen, as well as Japanese grilled dishes and bar snacks. The first Momosan was opened in New York City in 2016, and additional locations have opened in Waikiki Beach and Seattle, with another spot planned to open in Brooklyn.
Momosan is open for lunch and dinner, and I stopped there recently for lunch. The Lunch Menu is extensive, with Sushi, Cold & Hot Appetizers (about 20 options, priced $7-$14, with plenty of enticing choices, like Duck Tacos and Spicy Wontons), and Ramen (6 options, $16 each, such as Tonkotsu, Tsukemen, & Spicy Vegan Miso. There are other entrees as well, from A5 Waygu to Poke Don. I could have easily ordered several appetizers, to sample a range of dishes, but wanted some Ramen so chose to opt for only one hot appetizer.
I'll definitely be returning to Momosan soon, to try more of the menu, and maybe get some Sake.
