Best red meat in Seoul "Cobacabana Grill", a brazilian restaurant. If you want to eat meat, just go there! It is 29,000 KRW per person, and it is "all you can eat"!! Don't let the "all you can eat" fool you, because the meat is really really really delicious. The steak was so tender... Aaah. :) Meat lovers will be in paradise. There's not only red meat but also chicken, etc. I went there at 2:30pm on a weekday so the restaurant was empty but expect a lot of people if you go at night or during the weekend.
This is the dessert, pineapple with cinnamon and sugar! Delicious!!
