Good restaurants near National Kaohsiung Center for the Arts (Weiwuying)?

My favorite childhood teacher is coming to Kaohsiung to see an opera. I’d like to take her to dinner after the show, which ends between 5:30 and 6pm. Are there any good restaurants (not too loud so we can have conversations) near Weiwuying by foot or via the MRT? I know there is Stage 5, but it might be out of my budget (NT$1500/person). Since she will be heading back to Taipei the same evening, a restaurant near the Zuoying HSR station or near an MRT station would work too. Any help would be appreciated. Thanks!
