Just moved here from New York and last night decided to try Erawan on 23rd and Sansom because it looked tidy and pleasant even though there was n.o. o.n.e. in there.
My better half and I had Tom Kha Gai, the Erawan Noodles (wide noodles with spicy ground pork), the Green Curry, and mango sticky rice with condensed milk, all of which were really quite good.
The noodles were clearly handmade, the white rice - which I usually take for granted as being cold and stalely gummy - was very light and fresh though appropriately sticky. Both main dishes had some real heat and some complex flavors.
I haven't been to Thailand and I can't claim a well-educated palate in this area, but I think I can tell the difference between good cooking and the blandly sweet gunk you often find at run-of-the-mill American Thai places. In New York our favorite Thai place by a mile was the chowhound-famous Sripaphai. This meal at Erawan wasn't at that level, but it was definitely better than many of the meals we had at other places in NYC.
So how come we were the only people there from 7:30 - 9:00 p.m.?
