The first place I saw was the Hello Kitty House Cafe. I visited the Hello Kitty House on a Wednesday around lunch time and it was quite busy especially the cafe section. There was a 20 minute wait, and I noticed that there were seats outside for those waiting. So, after 20 minutes, the attendant called my number and I went inside the cafe. The cafe has two levels, all of which is decorated in ‘elegant’ Hello Kitty theme – very pink and fancy. When you get inside the cafe, there’s a counter to the left where you can order the different drinks and food. Many of them are of course, all Hello Kitty themed. I got the green tea cake and cafe latte. They tasted good, but I would say pricey (about $4USD for latte, $5 for cake) especially in Thailand. You can also order food for take-out at the counter outside as well.
Overall, the atmosphere, staff and food here are excellent. I would say (for now) the best Hello Kitty cafe food I have tasted.
