Mariel Underground Boston

Mariel Underground is at 10 Post Office Square. The venue pairs South American-inspired seafood with a playlist dominated by hits and reggaeton, creating a high-energy nightlife environment in the basement of the building.

The room runs dressier than the casual bars closer to the waterfront, making it the choice for those who prefer a club atmosphere over the standard downtown sound. It sits a fifteen-minute walk from Quincy Market, but the distance creates a necessary buffer from the tourist crowds. With a mid-range price point and a 4.69 rating from 1516 reviews, the venue sustains a level of intensity that the nearby markets lack once the dinner rush subsides.
