Dens: Yes, full of tourists. And yes, every one of your friends told you to go here. It's batshit crazy in a way you won't see batshit crazy in the US. Maybe get super cranked before you go.
Dens: This was rec'd to me as Best Ramen in Tokyo & it didn't disappoint. You order with 2 variables -- spicyness (I went 2 of 4) and numbing (I went 3 of 4). Numbing is amazing (& I'd rec'd going 4 of 4)
Dens: Long story short: My buddy said this was the best pizza in the world. I doubted him. I was wrong. Best pizza I've ever had. Get the margarita pizza, skip the marinara. You need the cheese.
