Personally, I think it is expensive. We werejust talking about that tonight. We are American, we do not like Thai food, we didn't back in the States, and we definately do not now. So Every trip to the store is a small fortune for us. We use as many Thai brands of things as we can, it is still very expensvie for us. Things here are never on sale like they are at home. You have to get used to the grocery stores here. They are a far cry from Kroger!
Going to the movies is very cheap. At home, for our family of four it would cost upwars of 40 dollars with tickets, drinks and a box of popcorn. For a family of four to go to the IMAX at Siam Paragon, you will pay a quarter of that. Internet and Cable are about the same. We have the minimum package and it runs around 45 dollars a month. Hot brewed coffee is expensive here. Almost everyone here drinks instant, Yuck! So a half a Kilo of your cheaper coffee will run you around 10 US dollars. I am a coffee junkie, so I have cut back quite a bit. The best coffee here is Suzuki, it is the better Thai brand of coffee. It is pretty good really. Still a lot to spend for us. Starbucks prices are the same here as they are in the States.
Electricity is a touchy subject. you have a lot of people who will steal you electricity, you also have a corrupt electric company who will pad the bills if you choose to live in a nice are. If you are from Europe or the states, you will want this. There seems to be very little middle income homes here.
Gas is about the same right now anyway....
The best asian beer here is Sinha. It will run you about 70 baht in any pub. That is a little over 2 US dollars. The Phone bill runs us about 10 US a month. There is usually not a gas bill here. Our stove runs on bottled gas, it usually lasts us about 6 months. It actually just ran out during dinner tonight. If you like traditional Thai food, you are good on the restaurants. You can eat very well here for about 5 US dollars, that is three meals.... I do not like thai food, so I have not been in any restaurants here. Mostly they are open air places set up on the sidewalks. 10 dollars US will buy you enough fresh local fruit to eat for a week at least. If you are an ex pat, you will need to find housing close to an international school. The tuition is not too horribly bad. We have two young children, we pay about 8 thousand US per semester per child. You also have to pay for uniforms, transportaion, etc. I live right next to the school, so my transportation is my two feet, they are free. I had my own vehicle in the States, and since I have been here, we only have one car, my husband uses it for work. I can honestly say, I have not missed the car too much. It really gets you out and about when you rely on a bike and walking. A lot healthier too. We live in Nonthaburi, which is a suburb of Bangkok. It is pretty pricy, but there is not much choice when you have school aged children. If you live downtown, your children will get on the bus at around 5 am and it will take them roughly two hours to ride the bus to school.
I hope this helps you. This is only my opionion, and I have only been here six months.
