I don't think you can find any better korean tacos in the city. The kalbi beef tacos never fail. They are juicy and delicious. I'm not a huge vegetarian fan but the veg kimchi fries and tofu tacos are amazing. I had never tried the Bao before but now I love them, they taste fresh and just the right size for a quick bite.
The sandwiches are great too, the portions are just right and fairly cheap. I love this place and would recommend it for a quick lunch if you're in the area.
It gets pretty busy there so your're not guaranteed a seat especially if there are more than two eating in.
