We discovered Grand Central Oyster Bar completely by accident. It's literally in the basement of Grand Central Terminal, which sounds sketchy but it's been there since 1913.

$1.50 oysters 4-7pm weekdays only. We ordered 24 oysters and a beer for $40 total. The vaulted tile ceiling is stunning and you can hear train announcements echoing above.

Pro tip: Show up right at 4pm to snag counter seats. The dining room fills fast with commuters grabbing drinks before their Metro-North trains back to Westchester.
