The lack of a good curry in Bangkok has been well documented on TD over the years, so it's always a surprise when I find a superior product out here in the jungle.
From my experience, the English Curry Renaissance started when The Bookhouse made an effort to give customers a genuine curry experience. They now offer a range of 6 English Curry favourites as part of a full platter. It's big enough to share with the missus and at 300 to 360 baht a pop, you'll probably want to, so not to use up to much of your 65 quid a week pension.
A more recent addition to the ECR is the Aussie Burger Bar's range of curries. Now, I know Aussies know curry like they know real beer, but fear not, Rob's curries are made by a real Englishman and are bloody excellent. The range of chicken curries are a reasonable 150B (I think) and are enough for two portions (unless you're a fat git). The Curry Meister will even take requests. This week I shall be mainly enjoying a lovely chicken Pathia (sweet & sour Persian stylee). Yesterday, I made the mistake of having one of his Phall's for lunch.
I shall endeavour to find some more curry delights in the fine colonial outpost of Udon Stani and report back. I might even remember my camera.
