Mardi Gras fans and Tulane grads, listen up: A Cajun-style restaurant is heading to Rockville Pike. Live Crawfish & Seafood is set to open this fall at Ritchie Center off Wootton Parkway, home to La Limeña, IHOP and a bounty of international restaurants. This will be a big place: 3,000 square feet with seating for more than 80 people, says owner Thuan Nguyen. Menu will be similar to that of New Orleans Cajun Seafood, a sister restaurant in Falls Church. (Click here to check it out.)
