Tiger Wok and Ramen is in the Caesars Palace food court. The lines here are long and kind of convoluted as there are people everywhere attempting to find something to eat. I tried the tonkatsu ramen which wasn't too bad but it was not the best I have ever had. Be aware of the sticker shock that comes with Caesars food though, as a bowl of tonkatsu ramen here costs upwards of $12-14 depending on the ingredients/extras you put in.
Oh. And don't get the bbq pork buns. They were a sticky, slimy, gooey mess.
