The following is the McDonalds food menu taken in June 2019. You may click on the image to view the enlarge menu:

In McDonalds Thailand, the food is not halal for example the chessy bacon fries. Certain selection like the burger and kapao rice comes with choices of beef – therefore you need to specify if you do not take beef.

At the moment they have the Samurai pork burger that comes with a set meal costing 109 baht and 129 baht respectively (depending if you order the single or double pork burger).

And the usual set of burger with fries and Pepsi. Aside from that, they have an interesting combination offer costing 119 baht (second picture above) where you can first choose your choice of burger, and then select another option to go with the burger (for example drumlets, fried chicken or nuggets) and combined with fries and drink. If you pay an additional 20baht you can also opt for upsize, meaning you increase the size of the fries and drink.
Similar with the McDonalds in Malaysia, here you can also select specific combination of 1 + 1 at 49 baht. For example, I selected a pepper chicken burger plus a chocolate sundae for 49 baht.

For coffee, they have the long black, latte and cappuccino available in hot or iced version. And not forgetting their Happy Meal where a toy is included as well.

Aside from strawberry and chocolate favour sundae, they also have the salted caramel sundae at 29 baht.

And they also have a selection of toppings you can add on to your desserts.

Overall we ordered the kapao rice with Pepsi set, 1 + 1 consisting of chicken pepper burger and Sundae (not pictured here) and the 119 baht set consisting of fillet O fish, fries and Pepsi set.
