I've been to Bullys numerous times, was thinking about going there tonight actually. Realized I haven't posted about it yet.
Bullys has some awesome American and English type foods, they do have a Thai section too by the way. They have tons of beers, including Duval, Hoegaarden, and of course San Miguel Light and many many more.

It's a pretty nice chill spot around the Nana area on Sukhuvmit.
