It’s an intriguing combination: Exceptional Vietnamese-style sandwiches plus delicious extras plus a fully stocked bar adds up to Rivière Modern Banh Mi at 905 N Hudson being an excellent reason to visit, and linger in, Midtown. James Nguyen’s menu packs a ton of variety into fresh-baked loaves from La Baguette, but start with the classics: the Miss Saigon’s pork and K*Pop’s bulgogi beef are both dynamite traditional tastes. And whatever you get, be sure to linger long enough to try a Vietnamese waffle made in-house with coconut milk and rice flour (the green hue is from pandan leaves) for a light, sweet conclusion.
