We have been to several Asian countries and we always get treated well and have a great time. It's hard to choose just one city in Asia, but Seoul is amazing. There are plenty of Korean BBQ restaurants all over the city and they are all good. They bring you raw meat, onion cloves, garlic, tofu, etc and your table is a grill. You cook the food yourself on the grill in front of you and it is a delicious feast to behold. If you have a big group, Karaoke is a blast. There are plenty of these throughout the city. You get a private room where you can drink and sing with your friends. Beer and Soju is pretty cheap in Korea so have fun with that.
