House of Thai, née Thai House Express on Larkin. After some head-scratching, I decided on a go at House of Thai's yen ta fo.
It was an appreciation of yen ta fo at Lers Ros Thai that inaugurated this blog nearly three years ago, and I was eager to revisit this pink marvel once again, to compare HOT's version with LRT's, insofar as my memory (and initial blog post's assessment) allowed. I won't belabor the dish with excessive explanation again, except to say it's a seafood (and sometimes pork) intensive rice noodle dish with a pinkish red broth derived from fermented, red rice colored tofu, sometimes with an assist from tomato sauce.
In sum, I'd say House of Thai wins with the toppings, but Lers Ros Thai wins with the soup, so I'd call it a draw. Both versions are bowls of noodles worth returning to.
Where slurped: House of Thai, 901 Larkin St., San Francico
