Marcus B&P (in Hahnes building) is a nice little date night spot.

Blue Steel Pizza in Bloomfield is a really cool spot with great food.

A bit further, but Rosemary's in NYC (18 Greenwich Ave) is our usual date night spot, and right off the Path

The Yard (military park) is underrated spot. Fast casual, and food is solid.

Urban Tandoor food (Indian) is fantastic, but I've never eaten there - only delivery. Pricey too.

I've heard Urban Vegan is superb, but I've never been so can't speak to the quality or ambiance. Think it's more fast casual than date night

Edit: just remembered! Charley in Harrison and the Vanguard are pretty solid too
