Arlington (later this year)
Back in the '60s, Gino’s East started when two taxi drivers and their good friend got fed up in Chicago traffic... so, naturally, they decided to start making gigantic deep dish pies. Gino's stands out among Chicago's deep dish purveyors for a cornmeal crust and a heavy (in a good way) hand with the sausage if you make it your topping of choice (you should). They've already begun their foray into Texas with locations in Houston and San Antonio, but a DFW location in Arlington is on the docket for 2015.
If you can't wait for Gino's (or just want to get your palate ready), Taste of Chicago in Addison does a respectable job with the deep dish, nailing the critical elements, like the over-the-top cheese payload and chunky tomato sauce. But when Gino's does arrive, definitely check it out -- word is, they're going to be incorporating a little Texas flavor (read: BBQ) into pizzas, which sounds like the start of a beautiful relationship.
