Busy place, but well worth the wait.
Went here on a Friday night with a group of 4 around 7pm - prime dinner time. We waited about an hour for a table, which wasn't all that bad. They text you when the table is ready, so that allows you to leave and grab a drink if you wish.
For starters I got the deep fried squash($11) and it was heavenly. It was a lot of food for a starter and definitely shareable between 4 people. It has had great presentation. Make sure you dip it in the sauce they provide you.
I ended up having the pad graw pow, with crispy beef ($16.50) and it was delicious. I'm not much of a spice guy, so I got it with medium spice and I found that to be perfect - it was spicy, but I wasn't reaching for my drink after every bite. My friend got the khao so and I had some - that tasted even better and I was pretty jealous. Next time I'll definitely have to get that.
Excellent atmosphere, fast service, great food and right in the heart of downtown - what more can you ask for. The price is obviously amazing considering where you are in the city and how busy the place is. They could probably charge double and only lose about 3% of their customers.
Will be back.
