"O Oysters," said the Carpenter,
"You've had a pleasant run!
Shall we be trotting home again?"
But answer came there none --
And this was scarcely odd, because
They'd eaten every one. -- Lewis Carroll, The Walrus and the Carpenter

There isn't an actual oyster bar at Magnolia Bar & Grill on Richmond, but during the Sunday brunch they put out a giant tub full of ice and line up freshly shucked oysters on the half shell among the cubes. Thanks to the efforts of an unseen shucker, they're replenished as fast as they're removed.

I've eaten a lot of oysters lately, and I greatly appreciate the efforts of a good shucker. Some poorly trained Houston shuckers run the oysters under tap water as they shuck them, to remove the grit of the shell. This results in oysters that smell and taste like chlorine. The shucker at Magnolia leaves a little shell behind now and then, but the oysters are carefully laid flat to retain their fabulous briny liquor.

Gulf oysters are at their prime this time of year. And when the water temperature in Galveston Bay is below 65 degrees Fahrenheit, the shellfish are also the least likely to contain high levels of Vibrio vulnificus bacteria (for more information, see "Sex, Death and Oysters," March 25, 2004).

Last week I commented that Galveston Bay oystermen gather up the undersized oysters prized by raw-oyster eaters and sell them to oyster bars that pay top dollar for them (see "I Am the Walrus, Part 1").

Since then, an industry insider has explained to me that in fact the oyster bars are doing the oystermen a favor by taking the little ones off their hands. The big money is in shucked oysters, and nobody wants small shucked oysters -- they shrivel up too much when you cook them. So I stand corrected on the motives of oystermen.

Standing in front of the big tub of tiny oysters at Magnolia's Sunday brunch, I have to keep my own baser motivations in check. With oysters selling for seven to nine bucks a dozen these days, you could recoup your $19.95 brunch bill pretty quickly by making a pig of yourself at the oyster trough. I try to restrain myself and leave a few for the other customers. That proves easy to do, thanks to the abundance of fiery chicken-and-sausage gumbo, buttery crawfish étouffée and creamy shrimp fettuccine on the buffet line.

Magnolia has been Houston's premier upscale Cajun dining room for more than 20 years now. The restaurant opened in 1983 during Houston's legendary Cajun restaurant boom. It was the Cajun craze that launched the Pappas brothers and Tilman Fertitta into the restaurant business.

Few of the Cajun restaurants that opened back then have survived intact. Many are gone. Some have changed the spicy recipes to become kiddie-friendly restaurants. Others began to cut corners, substituting frozen mystery fish for increasingly expensive red snapper.

But at Magnolia Bar & Grill, the food tastes exactly the way it did 20 years ago. That's partly because Magnolia's head chef, Gerardo Bernal, has been at the restaurant since the beginning. The other reason is because founders Jim Gossen and Jody Larriviere still own it.

Gossen and Larriviere were among the seven partners in the Landry's restaurant group, a gang from Lafayette, Louisiana, that was famous for bizarre partnership agreements. Thanks to the quirky ownership arrangements, when Fertitta bought the Landry's group, Magnolia Bar & Grill wasn't included in the deal.

We ended up eating brunch at Magnolia last Sunday by accident. I was trying to take my weekend guests, a chef and his video-producer wife who were visiting from Austin, to one of Houston's dim sum palaces. But they eat dim sum in Austin all the time, they told me. What they don't have in the capital city is high-end Cajun food, they said. And they begged me to find them some.

The array of Cajun classics on the buffet made Magnolia the perfect choice. We were all amazed by how good the food was. By complete coincidence, I had stumbled onto the authentic Cajun flavor that I'd found missing at Willie G's.

My discerning brunchmates skipped the buffet. They were far more intrigued by the exotic items on Magnolia's dinner menu, all of which are available at brunch. That made it possible for me to sample a whole lot of Magnolia's food in one long, languorous meal.
