Given that one of the first things Thais ask each other when they meet up is "Have you eaten yet?" it’s clear this is a nation that’s extremely passionate about its eats. You want to know how good a Thai restaurant is? Don’t look at the menu, the décor or even the prices. Look at the number of people inside. That’s your quality indicator. 

In celebration of Bangkok’s fantastic cuisine and the restaurants that have perfected it, we’ve rounded up 40 of the Thai dishes we couldn’t imagine living without. Some are world famous, others are more obscure, but they're all worth trying, at least once. If you've got your own favorite that we missed, let us know in the comments box below.

A precious favorite among Thais is a prized yam plah duk foo. At first, it seems to be a deep fried fluffy catfish essence of grease and air.

33. Pad Thai

Pad thai is probably the most famous dish outside of Thailand and something that tourists rave and hype about. So famous we almost didn't include it on the list. Medium sized rice noodles are stir fried with a host of ingredients like tofu, peanuts, shrimp, green onions, bean sprouts, garlic, pepper, fish sauce and lime juice. A scrambled egg mixed into the noodles seals the dish together and ensures deliciousness. Pad Thai is great to eat with a squeeze of lime and ground peanuts. Again, a spoon or two of sugar, chili flakes, and vinegar, are always an option by way of condiments. 

Pad Thai is available in countless street carts around the city. A stationary street cart is located right inside the gate of the Wat Ratchaburana (temple) near the Saphan Phut market. Chakkraphet Road, Wangburapha Subdistrict, Phra Nakorn District. Open in the late afternoon to late at night.

34. Guay Teow Rhua

Guay teow rhua is known in Thai as “boat noodles,” because the bowls of noodles used to be sold from boats. The sweet pork blood broth in every bowl is sopped up by a choice of noodles sen yai (wide rice noodle), sen lek (medium rice noodle), sen mee (angel hair rice noodles) or wun sen (glass noodles). A little bit of beef, pork, liver or pork balls, and a few sprigs of morning glory, are also added to the bowl. What makes the noodles special is that the bowls are small at about three to five bites, and an average diner can eat many bowls. Tables sometimes compete to see who can stack their empty bowls the highest. 

To experience the chaotic serving of boat noodles go to Sud Yod Guay Teow Rhua (Pa Yuk) ("Best Boat Noodle"), located at Victory Monument on the boat noodle alley, on the road heading towards Phahon Yothin. Open from 11am to 9pm. Tel: +66 (0)2 271 3178

35. Guay Teow Nuaa (Sen Lek)

Sen lek or medium-sized rice noodles are one of the more popular soup noodle choices. Beef noodles or pork and pork ball noodles are a handy lunch option. Broth, boiled for hours, is poured over a bit of tender meat with noodles, some light bean sprouts and maybe a little green morning glory, which steam in a boiling caldron before being put into your bowl. Though this dish comes chili-less, by now you will have built up a tolerance and will need to add a couple spoons of chili flakes for ultimate satisfaction.

An astounding bowl of beef noodles is available at Guay Teow Lookshin Disco Restaurant, 493/18 Thanon Ratchawithi (Victory Monument), Phaya Thai. It's a great place for lunch and open from 10am to about 3pm. Tel: +66 (0)2 245 6790

36. Guay Jab

Add celebrated rolls of wide rice noodles that look like one inch cigars to a thick light brown and fatty broth and you've got guay jab. Some other floating ingredients such as crispy pork skin, lungs, tongue and green onions keep the noodles company. The crucial overpowering flavor that signifies the dish is black pepper. 

There are a few great places to eat Guay Jab but for a wonderful experience head to Chinatown's Yaowarat Road, Soi Itsaranuphap (11). The street stall is open from about 5pm to midnight and always busy.

37. Guay Teow Lui Suan

Huge and thin rice noodles in the form of square tortillas are used as wrappers for these Thai style fresh spring rolls.

A wonderful guay teow lui suan can be found in a tent set up right outside of Tesco Lotus Hypermarket Pinklao located at 3 Baromraj-Chonnanee Road, Arun Amarin Bangkoknoi. Open from about 10am to 6pm.

38. Cha Yen

The answer to coffee and tea drinks from around the world is Thailand's very own and very sweet cha yen. We admit, it's not a food, but it's certainly deserving of a spot on our list as it's so damn refreshing. Though it is called Thai ice tea, the actual tea flavor is somewhat unrecognizable as it is overpowered by a huge portion of sweetened condensed milk and then heavily iced. Look for one of the many stalls with 'Carnation' advertising plastered all over them and there is sure to be cha yen. You can also order cha yen at all coffee stalls, drink stands or restaurants in Bangkok.

39. Kao Niew Ma Muang

Almost everyone loves yellow mango with sticky rice. A small bed of super glutinous rice is placed below some slices of super sweet, non stringy, ripened mango. Adding to the deliciousness is a drizzle of coconut cream syrup. Usually located at many makeshift stands depending on mango availability. 

You can find great kao niew ma muang on Phaya Thai Phahon Yothin Soi 1 Lue Cha. Fancier Thai restaurants will all offer the dish as a prized dessert.

40. Sang Kaya Fug Tong

A medium sized pumpkin is de-seeded and filled up with the creamiest coconut cream custard imaginable. When the custard hardens, the pumpkin is sliced like a pizza. A spoonful of candied pumpkin and coconut custard is then added. Sweet nectar.
