What's summer without a few dozen oysters? They don’t need their own special day but got one anyway, and we rounded up some deals beyond the usual happy hours.

BKB
321 E. 73rd St., Upper East Side
The big-city outpost of the Hamptons’ Bay Kitchen Bar is extending its $1 oyster happy hour to last the whole night, beginning at 5 p.m., with several varieties of East Coast oysters to mix and match. Specials also include the Montauk Pearl Oyster Ceviche ($4/piece) and Fried Blue Point Oysters ($24).

Flinders Lane
162 Ave. A, East Village
Australia has a sizeable Asian population, and that’s being showcased at Melbourne-inspired Flinders Lane. Today, they’re serving Oysters Kilpatrick, a classic (and offbeat, like many things Aussie) preparation with Chinese sausage and Worcheshire sauce ($18 for a half-dozen).

Bill Baker’s Restaurant & Bar
364 Grand St., Williamsburg
This newcomer pairs its beers and bourbons with American fare. Today, the $1 oyster happy hour begins at 4 p.m. as usual but keeps going all night, with mignonettes in Champagne vinegar for all.

Greenwich Project
47 W. Eighth St., Greenwich Village
Today’s special raw bar menu includes an assortment of chef’s choice butters, salts and sauces, with Gold Coast Steamers ($1) and Blue Whale Oysters ($2.75).

Nerai
55 E. 54th St., Midtown
If you’re willing to think outside the traditional oyster preparations, try this Greek newcomer serving $1 “with a twist of Greek.”

The Sea Fire Grill
158 E. 48th St., Midtown
Park yourself at one of Zagat’s favorites in the city and enjoy East and West coast oysters for $1.50 each all day long, served on the half shell, Rockefeller style or fried.

Surf City
1 Marin Blvd., Jersey City
This beach-by-the-city just debuted an Oyster Bar last Friday, which also includes clams, lobster, crab legs, shrimp and octopus to go with the 75 beers on tap and more frozen cocktails than you could drink all summer.

NYY Steak
7 W. 51st St., Midtown
The Yankees are playing the Red Sox this week, and the team’s steakhouse is doing a nod to the series with a half-dozen oysters ($6) split between varieties from Stony Creek, New York, and Barnstable, Massachusetts, all day.

Grand Central Oyster Bar
89 E. 42nd St., Midtown
Their “bivalve bonanza” includes a special platter of eight East and West coast oysters ($21.15) and a deal on their oyster of the month, The Naked Cowboy, for $2.55 each.  

Grand Ferry Tavern
229 Kent Ave., Williamsburg
Launched in time for Oyster Day but sticking around is a complimentary carafe of the restaurant’s Skipjack cocktail when you order the Grand Ferry Platter (12 oysters, 6 littleneck clams, 4 shrimp, $55).

La Pulperia
Hell’s Kitchen and Upper East Side
Before digging into their rustic Latin food, have a few oysters at just $1 each all day long at both locations.
