Our next DFW Burger Battle is a whole summer away.But it may already have a new contender: Mo’s Best Eatery.The Zaben family’s new, tiny take-out shop in southwest Arlington has been a fast success. Owner “Mo” Zaben is already talking about a larger location.Mo’s is known for huge sandwiches like the 1-pound Philly or 1-pound pastrami.Or the pizza, which Zaben calls “Northeast-style.”Or the shawarma and baba ghannoush, which he learned from family members and cooking in a Greek-owned restaurant in East Windsor, Conn.Or fried chicken, of all things.But on top of all that, Mo’s serves a gloriously juicy, drippy burger. It’s made from four cuts of beef, including New York strip steak and brisket, Zaben said. But it’s also seasoned and grilled to order.“I do my special blend of five or six spices,” he said.A one-third-pound burger ($6) came out much larger.“Mo” says he came to Arlington from Connecticut for a cousin’s wedding and decided to stay.“I looked around and there are a lot of chains but not enough local restaurants,” he said. “I decided to open really small and just see if it would work.”If he moves, it may be closer to Pantego or UTA. Students have taken to Mo’s.“I think I’d be ready for someplace bigger,” he said. (The current Mo’s only has a couple of tables.)Mo’s is open for lunch and dinner daily except Monday at 4004 Little Road, off West Pleasant Ridge Road behind a supermarket; 817-561-4522, mosbesteatery.com.Check out the cold stuffThe new Super Chix chicken sandwich concept in Arlington is booming. But don’t miss the frozen custard.The $1 custard has been the insider favorite since Super Chix opened. (It’s a new concept from Yum! Brands.)It comes in flavors such as raspberry-chocolate Nutella, mint Oreo, Nutter Butter or S’mores.Super Chix is open for lunch and dinner daily at 612 W. Park Row Drive, 817-795-1828, superchix.com.A weakness for Restaurant WeekIf it’s nearly July, it can’t be long till DFW Restaurant Week.The annual charity restaurant promotion offers discount dinners Aug. 11-17, with some restaurants extending the deals through Labor Day.“Reservation day,” when diners rush to book the best restaurants, is July 14.
