Austin’s Torchy’s Tacos chain will be opening a restaurant in the former Harold’s in the Heights retail space at the southeast corner of 19th St. and Ashland, according to a flyer advertising a new development planned for the former clothing store and connected space. Harold’s closed last year after operating for 61 years at 350 W. 19th St. The flyer says Braun Enterprises — which bought the fifties-mod property from the family of Harold Wiesenthal last September — has already executed the lease with Torchy’s, which is shown taking up 3,340 sq. ft. in the corner spot. The development includes an additional unleased 7,260 sq. ft. of ground-floor space imagined as a cafe and 3,000 more sq. ft. upstairs shown as a dental office in the flyer.
