Why should you go?
Thai Diner (aka Uncle Boons 2.0) is one of the most popular if not the most poplar Thai restaurant in NYC that tourists generally dont know about. Dont worry locals, I’m not gonna change that as I dont have that kind of reach. But sharing is caring. One way you can check whether a place is touristy is simply by looking at Trip Advisor reviews compared to the more local Yelp, and Google. A whopping 26 reviews compared to 871 (Yelp), and 1569 (Google). Thats as local as it gets for a Manhattan establishment.
It took me a few visits to warm up to Uncle Boons, but I’m beginning to like Thai Diner even more. The space is more welcoming, and more comfortable (emphasis on more than the predecessor which was fairly uncomfortable). Love the decor, the Pure Thai Cookhouse-like Thai music. I never understood why so many ethnic places play American music. Who wants to listen to Sweet Caroline while munching on Szechuan food. Well, according to Trevor Noah its every single white person, but you know what I mean.
When should you go?
Its always busy, and waits are inevitable. They take a very limited number of reservations, so you can pretty much forget about reserving. But that just means you have a better shot at getting a table than popular places that do take full reservations. I call it the Via Carotta effect. If you are like us and have no problem combining lunch and dinner, than 4pm is your best bet. Even on Sundays there was no line at 4. By 6pm you are well fed and you are good for the rest of the day. Otherwise, come earlier, put your name down, and play tourist in NoLita/Little Italy/Chinatown.
What should you eat?
Its a smart mix of creative and classic. Every meal for many of us starts with the sick Disco Fries and ends with the Coconut Sundae. The latter is a masterpiece that includes candied peanuts, coconut gelato, coconut caramel, and to add much needed coconut flavor, toasted coconut. Another must is the crab fried rice. The Khao Soi is very solid but messy to share if more than two. The Turmeric Roti with the curry dip is terrific, as well as the Phat See Ew with fried chicken (some prefer the other chicken option, but I like the fried). The only dish I’d avoid is the Green Curry with braised beef. Sounds great, but large chunks of meh quality beef isnt doing it for me.
Who should you bring?
Ok, this survival guide is getting ridiculous Ziggy. But hear me out. This is not your typical Thai eatery in NYC where I normally have to do some begging for a little bit of heat. And while its not exactly “Thai spicy”, BYOB (Bring your own Bounty) like Ugly Baby, its bald flavors arent for everyone. Since the spoiled Mrs Z doesnt always remember the names of places we visit, I have to refer to them in other ways. Thai Diner is the “coughing place” after a memorable spicy coughing attack one time. Meaning its not the place for your mother in law’s 70’s bday celebration. Take adventurous eaters that appreciate good food and can handle a bit of heat.
What about Brunch?
Yes, please. This is one of the areas that sets Thai Diner apart, and where the creativity shines. Its a popular Brunch option for many, and one of the reasons is the outstanding, hurt so good, egg sandwich. Its wrapped in Roti that absorbs much heat so its a bit difficult to hold with bare hands, but its worth it. Thai flavors mixed with eggs, even in the morning is like magic. The Thai Tea Babka French Toast is popular as well.
What should I wear?
Khakis, loose clothing, funeral sunglasses for those not used to bald flavors.
As we get older, mental lists get less and less effective. We start to forget things, and sometimes get in trouble as a result, especially with the spouse. The saving grace is an equally forgetful spouse, but not when she has different habits and writes everything down.
