Oma’s Jiffy Burger, a Waxahachie institution, celebrated its 37th birthday Friday morning, hosting a KBEC 1390 remote broadcast. While Oma Shaw, the restaurant’s founder, was not able to make it to the celebration Friday morning, she did send along her best wishes to the man she sold the business to back in April of 2000, Jimmy Poarch. Oma’s, located at 403 Water St., is open for lunch and breakfast and has been ranked No. 2 in the state of Texas for its hamburgers.
