I am always pleased and quite full when I leave here. Don't bother with Pho Mailan up the street, you can read my post about them as to why. It's better than Lemongrass which is almost across the street.
As for the people whose problem with this place is service.... In my not-so-humble opinion, crappy service is quite common in southeast Asian cuisine restaurants. Many seem to lack any personality, and any server etiquette. Same applies here. But the food is consistently great and I've never been let down.
