The Mermaid Inn: Chelsea Seafood With a $2 Oyster Happy Hour (All Night Mondays)
The Mermaid Inn is the little New York seafood group known for one thing above all: a cheap oyster happy hour. At the Chelsea location on 10th Avenue, it’s $2 oysters and littleneck clams — all night on Mondays, and 4:30 to 6pm the rest of the week.
It’s upscale-casual — a proper seafood room, not a raw-bar counter — with the same deal running across the group’s other spots (an Upper West Side location, plus the Greenwich Village and Times Square oyster bars). Drinks at happy hour are fair too: $8 drafts, $10 wine, $12 cocktails. The oysters are the reason to go.
The Happy Hour
It runs all night on Mondays and Tuesday through Sunday, 4:30 to 6pm. The deal: $2 chef’s-choice oysters and $2 littleneck clams by the half-dozen, plus $8 draft beer, $10 wine or a Hugo Spritz, and $12 cocktails. There’s happy-hour food too — $4 clam chowder, $4 mini fish tacos, $9 sliders, $12 calamari, $10 salmon tartare. It’s an early-evening (and Monday all-night) deal; confirm the window at your specific location, since the group runs several rooms.
The Room
The Chelsea room is at 227 10th Avenue, near 23rd Street — a warm, upscale-casual seafood spot, open from 4:30pm with weekend brunch. Beyond Chelsea, the group’s Upper West Side location on Columbus is now open, and the Mermaid Oyster Bars in Greenwich Village and Times Square run the same oyster deal. Nearest train to Chelsea is the C/E at 23rd Street.
