Le Viet at Siglap
The broth here is a bit too heavy-tasting for my taste (and slightly artificial - I suspect they use some MSG-based cubes to help), and the bowl is pretty small. I still prefer the lighter, more delicate and natural taste of Pho Hoa. The fresh rolls were fresher than Pho Hoa's though (Pho Hoa's rolls suck - like they had been sitting around for a few days).
This actually used to be the same shop that was outside Far East Plaza, which has now closed, so the only one is this Siglap one. (I wonder if any kids pour chili sauce in the open guppy tank by the tables at this location.)
