This place is always a safe bet when in the area and/or in need of a Thai fix.
Just like zi char, it's always a great idea to pull along more friends to eat their other sides. I've been to their other branches but I think the one here trumps in consistency and taste.
Any more aunthentic than this, you'll be sitting by the roadside tables in Thailand (though there are tables perched by the kerb here already...)
