We picked up the takeaway menu from Cocos and noted the nicely decorated room and non-Thai serving staff dressed in lovely Thai silk sarongs, but looking at the descriptions of some of the dishes, and the missing standard items we look for, we had some doubts as to their claim of "Authentic Thai Cuisine". We drove past Thai Lemongrass on the way to Dunsborough and called in on the way back to pick up a menu.
The restaurant is in an old service station, next to Dominos pizza and is mostly a large open kitchen with 4-5 small tables in a plain area for those that want to eat in rather than take away, so not the place for a night out like Cocos would be. The people are all Thais and full of smiles when we ordered some of the dishes "Thai pet pet", the food was ready in about 15 minutes on a quiet Sunday night.
We ordered (take away) some of our favourites (all off the "Specials" page), chicken larb, jungle curry (seafood this time), som tam thai and a fish choo-chee. We ordered the larb "Thai-spicy" and it was, authentically flavoured and delicious, the chicken more coarsely cut than is common, but nicely presented. The jungle curry is only offered "hot" and it was as good as any we have had in Australia, probably too spicy for many people though. In deference to the others eating with us we ordered the som tam mild, but it was still a good effort for a dish not always offered in Aus Thai restaurants. The cho chee fish was nicely flavoured and mild, not all coconut milk and nothing else.
There are a lot of other dishes on the menu for those used to Westernised Thai/Chinese food, but anyone who really knows Thai food would know to mostly avoid those and go straight to the "specials" on the last page.
I'd be very happy to have this as my local Thai take-away.
