We went to Mango Tree on Surawong the other week for a friend's birthday. They have something called a Pad Thai Phuket Lobster that they were charging the princely sum of ฿2,900++ for Medium and ฿3,800++ for Large.
Too rich for my blood so we didn't get one. I saw one being delivered to a table and it didn't look very impressive so unless I find a hi-so girlfriend I won't be trying it any time soon.
