Thai food is not eaten with chopsticks, but with a fork and spoon (except in noodle shops). 
The spoon is held in the right hand and the fork is used to push food onto it. Since Thai food is prepared in small pieces their is no need to have a knife.

Ideally, eating Thai food is a communal affair involving two or more people, principally because 
the greater the number of diners...the greater the number of dishes ordered.
 
Generally speaking, two diners order three dishes in addition to their own individual plates of steamed rice, three diners for four dishes and so on. Diners choose whatever they require from shared dishes and generally add it to their own rice. Soups are often enjoyed concurrently with rice. The spicy dishes are balanced by bland dishes. 

The ideal Thai meal is a blend of spicy, subtle, the sweet and sour, and is meant to be equally satisfying to all the senses. The typical meal might include a clear soup, a steamed dish, a fried dish, a hot salad and a variety of sauces to use for dipping. This might be followed by sweet desserts and/or fresh fruit. 

There are approximately 40 spices & herbs that go into the various Thai dishes served. Some are used only as taste in the dish and should not be eaten. Yet some like, sesame seeds, spring onions & the mandarin orange, are entirely edible  and indeed are expected to be eaten as a part of the dish.

Thai food is generally not served in courses. All dishes are ordered together and eaten in what ever order they arrive. Also bear in mind that meats mentioned in most dishes are usually interchangeable and can often be substituted with vegetables. You’ve now heard so much about Thai food you are ready to order but the problem is, you’re not familiar with the different dishes or what to order in a Thai restaurant.
