“They’re called hungry ghosts for a reason. When you die and get stuck on Earth, you get confused. Your physical self is gone, but you stay hungry, as if you were still alive. That’s why they hang out at the best restaurants. Which must suck, to be honest, since they can’t actually eat anything. Anyhoo, that’s how you know where the food is the best. It’s way more accurate than Yelp or Foursquare.”

I’m impressed by Taeyo’s knowledge. He obviously did his research for the app.

“Well, that’s easy,” Emmett says. “Seoulful Tacos.”

I nod eagerly. “It’s a Korean-Mexican place run by a Tokki family. It’s our fave.” In fact, everyone in LA knows David Kim’s family restaurant is the best in town. Just the thought of their gimchi guacamole and bulgogi tacos makes me salivate.

Taeyo points to the new-and-improved Boris. “Great. Who wants to drive?”

I shake my head. “He’s too small for us all to…” I stop in mid-sentence. “Well, actually, I guess he is big enough for the three of us now, thanks to you.”

Emmett quickly jumps on Boris before either Taeyo or me. “I’m driving,” he says. He leans into the scooter’s ear and whispers, “Sorry for leaving you behind before. Nothing personal, but hey—you’re looking pretty good for an old dude.” The dragon’s tail wags happily.

I jump on behind Emmett, and Taeyo takes out his phone and raises it above us at a high angle.

“What are you doing, weirdo?” Emmett asks, looking sideways at him.

“I’m taking a selfie of us. I’ve never gone on a mission with friends before, and I don’t want to forget it.”

He’s so sincere it makes me laugh, and I’ll admit—it feels good. I lean in next to Taeyo and smile hard for the camera. “Gimcheese!”

Emmett glares at me. “Are you serious? You guys are losers.”

Taeyo and I pull him into the shot and Emmett groans. “Okay, fiiine,” he relents. “But make sure you don’t get my bad side, or else I’ll hurt you. My nails are sharp. Just saying.”

19: Anyone Hungry for Seoulful Tacos?

WHEN WE WALK IN THE DOOR of Seoulful Tacos, the waft of smoky barbecued jackfruit and fresh gimchi salsa has me drooling. It smells so good in here, and I can’t believe how famished I am.

Taeyo grins as he looks around the restaurant. “Whoa, there’s loads of people in here. It’s going to be a hotbed for gwisin!”

“If you say so,” Emmett mumbles.

I’ve been here a million times before, but today I look around nervously as if I’m entering the place for the first time. Thankfully, I only see tables of live humans eating and ordering food. Phew.
