Definitely lives up to the hype! It's busy at all times but if you're a small group it shouldn't be too hard to get a seat. They pack people in tight like a can of sardines so don't expect much privacy or quiet. Service was about what you'd expect in a packed place, food came quicker than i was expecting and appetizer arrived in minutes.
Food was amazing. We ordered the Fresh Rolls as a starter, which is a pretty standard thai dish but their dipping sauce was really impeccable (just the right amount of heat for an appetizer). As our main course we shared a chef's special pad thai (chicken) and a pad gra prao (minced beef on rice). The pad thai was greasy and delicious, I like how they put a twist on the standard pad thai (noodles+sauce made it a bit soggy but i think that was on purpose because it tasted awesome). The pad gra prao tasted good as well, but was kind of overshadowed by the pad thai. It's a pretty common dish, but i enjoyed the way they made it (nice and filling).
If you like spicy you might want to go hotter than medium, which was more of a slow burning aftertaste, than a sweating forehead hotness.
