Upscale dinner for a group?

Hey everyone, visiting BKK with some friends from NYC in June and looking for a nice upscale spot with great food that can fit about 12 pax, around 5,000 per person. Open to tasting menus and Michelins but also open to upscale hidden gems or hot new spots. Would prefer some type of Thai or Asian fusion, not too pretentious and stuffy. 

Some spots I was considering: 

Khao 

Sri Bua 

House on Sathorn 

Blue Elephant

Wana Yook 

Taan

80/20

Open to any other recommendations! Looking for a great atmosphere, good drinks as well. We’re all from out of town so going off TripAdvisor and Reddit recommendations. Thanks in advance!
