Taco Twist, formerly located where North Parramore Avenue ends at West Colonial Drive [GMap] has closed.
Taco Twist always offered Korean tacos, as they were owned by the same owner as the Korean BBQ Taco Box.
Replacing it is a new concept called Bulgogi House. According to Facebook, the Taco Twist page and the Mex Korean Kitchen page were recently merged, undoubtedly a precursor to a new Bulgogi page being launched in the near future. There is no website.
