I've been wanting to make pad thai, and all the recipes I find call for fish sauce.  I've never bought or used fish sauce, so I Googled to find recommended brands.
Then I went to Choi's Asian Market.  I saw three brands.  Two of them were poorly reviewed in an article I read, so I ended up buying the third.
However, the third brand-- Dynasty Premium Fish Sauce -- has virtually no reviews that can find, anywhere.  No one mentions it anywhere, at least in English.
Since I have no experience with fish sauce, I have nothing to compare it to, so I won't really be able to review it myself.  Not with any bases for comparison, anyway.
I feel like a pioneer. It's kind of scary.
