Sorry if this has been covered before, but "S&I" gives frustratingly broad search results.
The general opinion on S&I is that it's not that great if you order off the English menu, which is exactly what I did as someone who doesn't read or speak Thai. Asking about Thai-language specials pictured on the wall just got a "you don't want that". I was very disappointed with the food we got (I ordered a spicy pork dish that was mostly fat, and my wife got burned pad see yoo), but given all the positive reviews I'm willing to try again. What should I order next time?
