I came in with the misconception that I would need 5 things off the menu to make it a meal. I was full after two asada tacos and a sopes.
The lines were long for 5pm, but there was advantage to that-- it gave me time to observe how other customers ordered. There are three lines depending on the type of meat you want, so if you have a party, you should split up. Grab a tray when you're in the front and ordering, and take your food to the cashier on the side. They accept cards.
I'm not sure where the sauces were, or if it's even available. They have long scallions (no forks) that you can possibly get from the middle (I'm not entirely sure, I had to ask another customer). I wasn't a fan of these--a little too slimy for me.
As for the food ordered, the asada was good and I'd recommend the lingua sopes. I was full after 3 items. The fries counter had at least 30 people in line so I didn't try that.
It is mesmerizing to watch the cooks do the motions of building each menu item so quickly. I'd come back again.
