I suggest that you guise be prepared on what to see and what to get at Comiket at the Tokyo Big Sight.
Usually its a 3 days event, each day is different themes (they probably change it over the years).
Day 1 is for general, Day 2 is for girls, Day 3 is for ehem.
Booths of artists works are all around from those huge Hall 1 to Hall 6, so if you do not know what you are looking for, you might not enjoy it much.
However, if you are more of those commercial booths fans, the top floors usually have lots of them.
As always, the cosplay areas are located outside the halls and sometimes outside of the top floor.

Do note: Comiket is way different from Wonfes.
Wonfes is more of commercial booths and toys.
Comiket is more focus on artists works.
Which one is more meriah?
That will depends on what you think
*to me, I prefer Wonfes*

YES

Yes, the 3 prawns big bowl is my favorite
Just enter the shop, sit down, and say "abe ten o, gohan omori desu" (nasi 3 udang satu, kasi nasi tambah)
Now already got McPork, but I think only certain McDs served them (or was it by seasons, I dunno).

How's the plan coming along, guise?
When is Air Asia gonna start coming to Japan (or is it ON already?)
