Been to Kinn Thai twice now for lunch. Both times the food was excellent with service to match. As others have mentioned the crispy pork belly is so good. Liked that they had the normal menu + a lunch menu as well. Don't think the lunch menu is on display at the entry point, only the main menu, which appears to be a slightly dearer version - lunch menu is well priced with a good selection.
Kinn Thai must be doing something right as the lunch crowd queue for a table, but it is worth the wait as the food is so good. Will be back.
