Dallas restaurant news this week is happy-cheerful, as it's all about openings, not closings. Smileys all around.

A Cajun seafood place called Tasty Tails opened in the Asia World Market food court on Legacy Drive and 75 in Plano. Seafood options include crawfish, boiled shrimp, fried oysters, catfish and soft-shell crab. Tasty Tails also does po' boys, crawfish pies and meat pies, plus side dishes like sweet potato fries, "Cajun" fries and calamari fries.

HG Sply Co., the lower Greenville Avenue restaurant that espouses the Paleo diet, opens May 21 – begging the question, does eating a Paleo diet hinder your ability to spell correctly? Owners Elias Pope, Gus Antos, Mark Zahem and Neville Govender, who took over a keen spot with a rooftop deck that used to be such memorable clubs as Lost Society and Suede, found their perfect chef in Paul Niekrasz, who was chef at One North Kitchen & Bar in Chicago. Now if only they can find those missing letters, "up." HG Sply opens for dinner only at first, adding lunch in June.

House 34 is a new restaurant opening in Uptown next-door to Belly & Trumpet on McKinney Avenue, from SMU professor Teresa Brentagani and her husband. Managing the place is Michelle Avila, who previously worked Old Warsaw; she's joined by former coworker and Old Warsaw chef Andres Bautista. Avila says they hope to be open by the last week of May, and they'll serve breakfast, lunch and dinner. "We'll have omelets, salads and paninis at lunch, and sea bass and filet mignon for dinner," Avila says. "It'll be upscale and very trendy, with a Mediterannean look but an American cuisine."

The new Cane Rosso White Rock, having survived the craziness of its late-April opening, has expanded its hours and is now open for brunch/lunch on weekends. (If you monitor the Facebook page, you see questions about the hours posed almost daily; those Lakewood residents are a tough audience.) The restaurant is now open 11 am-11 pm Saturday and 11 am-9 pm Sunday. This is in addition to the regular dinner hours of 5-10 pm Monday-Thursday and 5-11 pm on Friday.

Citrus Bistro, which shut down its Preston Royal location when its lease ended in March, will reopen in June in Colleyville. Chef Didier Viriot and his wife Nanou live in Richardson and were considering Allen, but they liked how young and prosperous Colleyville felt, says Nanou. They're taking over a space previously occupied by an interior design store and will serve signature items such as fried calamari and their date cake dessert.
