Hoi Tod is a Thai dish made by frying mussels (or sometimes, other shellfish, squid, or shrimp) in an eggy batter and wrapping up beansprouts and garlic chives with it. Those in the know usually prefer this dish to Pad Thai. It’s often served as street food, especially at night markets, but there are also small shops that specialize in it.
This particular joint was crowded when we visited at lunchtime on a weekday in a busy Bangkok district, but I thought it was pretty average — I thought it was too stuffed with undercooked sprouts, but that might just be due to my preferences. I’m used to a greasier dish with a more generously seasoned finishing umami punch in the gut. I thought this hi-so version was a bit bland. Also, eating this in a restaurant instead of at a fold-up table on the street means it costs double… However, in the third pic, you can see that they served a whole extra plate of crispy bits on the side, so that almost made up for it.
