Ready for some food fun this week? Here are a handful of events taking place in Austin over the next week:

When we first started hearing about the Paleo diet, most of us in the food world thought it would be a short-lived trend that would fade out as soon as it popped onto our radars.

But just a few years later, it seems as though the grain-, sugar-, dairy-free "ancestral" way of eating is growing as fast as ever, and later this week, one of the biggest Paleo events in the world will take place in Austin. The third annual Paleo f(x) Symposium will feature more than 140 authors, athletes, speakers, fitness trainers, entreprenuers, physicians, cooking instructors and more who will present Friday through Sunday at the Palmer Event Center, including cookbook authors Michelle Tam ("Nom Nom Paleo"), Dallas and Melissa Hartwig ("It Starts with Food") and Melissa Joulwan ("Well Fed").

Three-day passes cost $324, and single-day tickets for the expo are available for $20 for adults, $10 for children. More information at paleofx.com.

Virgina Willis, one of the most-respected voices in Southern food today, is hosting a pop-up dinner at Central Markets across Texas this week, including a stop at the North Lamar store on Friday.

The dinner, which starts at 6:30 p.m., will feature dishes including Gulf Coast crab cakes with rémoulade, vegetable soup with okra gougeres, roast fresh ham with herb jus, parmigiano reggiano grits & spring greens, and banana pudding with salted caramel. Tickets cost $70 at centralmarket.com/cooking-school.aspx.

Thanks to the colder-than-average winter, crawfish season has been slow to start this year, but the mudbugs are starting to come in (and at better prices than just a few weeks ago) just in time for the 20th annual Louisiana Swamp Thing and Crawfish Festival 11 a.m. to 10 p.m. Saturday in the parking lot of the Austin American-Statesman, 305 S. Congress Ave.

Tickets ($20 at roadwayevents.com or at the gate) include an array of live music and a plate of crawfish, but other foods will be available for sale. There also will be arts and crafts, face painters and children’s activities at the event, which is sponsored by Stuffed Cajun Meat Market.

The four urban farms in East Austin were in the news quite a bit last year, but now that the new urban farm ordinance is underway, the farmers at Rain Lily, Springdale, HausBar and Boggy Creek are busy keeping up with spring crops and presenting their fifth annual East Austin Urban Farm Tour.

The event, which is a fundraiser for the Farm and Ranch Freedom Alliance, will take place from 1 to 5 p.m. Sunday at each of the farms, which are located within walking distance of one another just off East Seventh Street. At each location, guests can sample small bites from a number of Austin restaurants including Qui, Kome Sushi Kitchen, Wink, Lenoir, Bufalina, Cafe Josie, Olamie, Hillside Farmacy, Bola Pizza and Peche. Drinks on the tour are from Austin Wine Merchant, WeatherUp, Live Oak Brewery, Paula’s Texas Spirits, Dripping Springs Vodka and Wahaka Mezcal. Tickets ($50) are available at eastaustinurbanfarmtour.com.
