The whiskey-and-cocktail satellite of the Cable Street original, OB Noodle House Bar 1502 operates a Niagara Avenue dining room with a focused Vietnamese-and-pan-Asian kitchen and an extensive American whiskey, peanut-butter-whiskey, and craft-cocktail bar. The Niagara location drops the bun vermicelli, Vietnamese BBQ, and teriyaki plates carried at sister concept OB Noodle House & Sake Bar, narrowing the menu to pho, pan-seared crispy egg noodles, Hong Kong chow fun, dry chow fun, sizzling plates, and Saigon fried rice. The $5 Asian-style pork-belly tacos — Korean-style grilled belly with house-made papaya salad, sriracha aioli, and cilantro — sell singly or in three-for-$13 sets and were the dish that picked up televised national coverage. Late-night cocktail traffic on Niagara overlaps with the after-dinner martini-and-spirits crowd at Tony's Martini Bar on Newport, with both rooms drawing the late-evening spirits audience that other corridor kitchens release. The peanut-butter whiskey shot program — a signature spirits selection developed in-house — anchors the cocktail bar's most-distinctive product line and pairs with the late-service wing-and-fish-plate menu that runs after most surrounding kitchens have wound down.
