Nosh on select $1 oysters, weekdays from 3 to 6 p.m., at Little Italy's jammed seafood hot spot. Other critters at the raw bar include bivalves, crudos, and crab claws.

It's OK to be a little shellfish and splurge on Sundays, when $1 oysters are served up 5 to 9 p.m. (rotating options include kumamoto, bluepoint, and fanny bay). Pro tip: get there early because $1 oysters last all night, or until they run out.

This longtime Gaslamp staple has seafood lovers hooked for a reason: $1 oysters shipped all the way from the bays of British Columbia and shoals of Montauk. Slurp 'em down weekdays, 5 to 6:30 p.m. While you're at it, order the $2 jumbo shrimp, $5 featured wines, or $4 draft beers.

One Yelper has a devious tip: "Be at the doors at 4:50 p.m. so you can be seated right at 5 to have everyone enviously eyeing your platter of oysters before they even get water." The $1 deal goes 'til 6 p.m.
