I think local chains are like City Garden are fine

But I have no experience with City Garden myself . I would charge it, and try and call Shacom 2818 8236 before leaving the restaurant to have them confirm the MCC. Void and charge to another card if not 5812.
I kinda miss their call centre, was one of the better ones. May get a little hard to get through during busy hours but definitely nothing like calling HSBC CS non-Premier these days.
