Here is the list of best dishes to eat in Bhutan:
1. Ema Datshi

'Datshi' in the Bhutanese language of Dzongkha means 'cheese', which is what they use in a number of dishes, the most popular being Ema Datshi which is like a stew made from chilies and cheese ('Ema' means chilies) and might prove to be too spicy for some. Bhutan's national dish is unarguably the country's most popular dish, and any discussion about Bhutanese food cannot go without the mention of Ema Datshi.The chilies are split lengthwise with their seeds and ribs removed and are mixed with cheese, garlic, water, and some oil. Is this a special kind of farmer's cheese that doesn't dissolve in water and is hardly found outside this nation? Onions and tomatoes are also added sometimes. Yak cheese might also be used. There might be small variations in the preparation of Ema Datshi throughout the nation (such as the consistency of liquid), but the ultimate essence remains.Other variations of this dish is worth trying.
2. Shakam Datshi

Shakam Datshi is another form of this dish that is made from dried Bhutanese beef, which is a very popular meat. The beef is dried and preserved but not completely dehydrated. This is then simmered in cheese and butter.
3. Khewa Datshi
Khewa Datshi involves chilies with potatoes that are usually cut into thin slices and then cooked with cheese and butter. Tomatoes and chilies may also be added for some flavor. Shamu Datshi consists primarily of mushrooms and cheese and is prepared similarly. These dishes are eaten with a generous helping of red or brown or white rice.
4. Red Rice

Except for the Bumthang region where buckwheat food items are more popular, red rice is one of the staple foods of the Bhutanese people. It is a medium-grain variety of rice that is grown in the Kingdom in the Eastern Himalayas. It has been grown for a number of years in the fertile soil of the Paro Valley which receives the benefit of mineral-rich glacier water. It cooks faster than other rice varieties because it is only partially milled, i.e. some of the bran is left on the rice and after being cooked acquires a reddish-brown tinge. Being gluten and wheat-free and rich in minerals, it is highly nutritious as well. This rice is earthy and nutty to taste and goes well with dishes with a bold flavour. The Bhutanese often accompany this with dishes containing mushrooms and chillies such as Ema Datshi, Shamu Datshi, Khewa Datshi and some other cheese-based and meat-based dishes as well.
5. Jasha Maroo or Maru

Another dish worth tasting would be the Jasha Maroo which is like a spicy stew or curry which is made with diced chicken, onion, garlic, chillies, tomato, ginger and coriander leaves. Ginger gives this dish its essence. It may be served with a generous portion of chicken broth. Beef may also be used in place of chicken. This is usually served with red rice as it is in case of most Bhutanese dishes.
6. Phaksha Paa

7. Shakam Paa
Shakam Paa which is rich in protein, consists of dry beef slices cooked with dry chilies, potatoes, onions, and radishes. It is mostly cooked in a pot and served alongside a portion of rice.
8. Sicaam Paa
Sicaam Paa is another version of this dish that employs sun-dried pork belly, which is then fried along with dry chilies.
9. Yaksha Shakam
Yaksha Shakam is a version of this dish that substitutes pork with dried yak meat.
10. Suja

11. Ara

Ara (or Arag) is the traditional alcoholic beverage in Bhutan. It is made by fermenting or distilling rice, wheat, maize, millet, barley or buckwheat and is usually creamy, whitish or clear in appearance. It has a very strong smell and taste. Sometimes Ara is also heated with butter and eggs to make it a more wholesome beverage. There are also other drinks like Banchang and Sinchang which are made by fermenting grains with homemade yeast. Sinchang is a cool drink whereas Banchang is a hot drink.
12. Zow Shungo

13. Jaju Soup

14. Jasha Tshoem - Spicy Stew

Jasha Tshoem is a spicy Bhutanese stew prepared with beef and flavoured up with ginger-garlic, onions, chilli pepper and sometimes mushrooms.
15. Khur-le

Khur-le is a traditional hearty Bhutanese breakfast, ideal for cold climates. It is a pancake made out of buckwheat, barley or wheat flour. It serves as a good combination of other Bhutanese dishes like ema or shakam datshi, or with eggs and sauces.
16. Puta

17. Momos

Having migrated from Tibet and Bhutan to many regions of India, especially north India - momos have firmly established themselves as one of the most popular street foods, and give serious competition to the likes of chaats and vada-paavs, the traditional Indian street favourites. Bhutan serves some extremely tasty options for this snack. These steaming hot dumplings have a variety of stuffings - including minced beef, pork and other meats, as well as vegetables like cabbage. Cheese momos, mixed with spices, are also a popular option. Apart from the steamed varieties, there are deeply fried momos as well. They are eaten with hot chilli sauces called ezay.
18. Hoentay

An alternative to the famous dish of momos, Hoentay originates from the Haa Valley of Bhutan. They are made from the Bhutanese buckwheat and are steamed or fried with different stuffings of green leafy vegetables, cheese and meat. They are also served with the Bhutanese chilli sauce ezay.
19. Khatem

Khatem is a preparation of bitter melon or bitter gourd, generally the Indian variety. It is sliced up thinly and fried in butter, and seasoned. It is a tasty snack for all times.
Some other food items to sample when in Bhutan would include momos, dumplings which are made with buckwheat and are filled with spinach, cheese, turnips and other ingredients, eaten with a spicy sauce called Ezay and which are a speciality of the Haa Valley along with other buckwheat dishes. Goep is another popular dish which is made with tripe which is stir-fried with green onions, chillies and vegetables. The list doesn't stop at that. As one explores more, one will come across more exotic dishes (probably not any less spicy) and leave with an overall wonderful experience of tingling taste buds.
