Homegrown Japanese grill Mr. Teriyaki is preparing to open second location, this one in the busy Westover Hills area near Tom Slick Park. The San Antonio-based business raised the the curtain on its expansion plans earlier this year in an Instagram post. Now, a March 5 Texas Department of Licensing and Regulation filing shows work will begin on a location at 8603 Texas Highway 151, Suite 109, in mid-April.
