I work just down the street. It was a good new spot to try from my normal China-town routine.
The place was empty when I arrived at 11:40am, and stayed pretty empty for the next hour. It's decorated with a little gastro-pub feel. you order at the counter and wait for ur food.
I got the "Frank's got seoul", and my friend got "Frank goes to buffalo". To be honest, it looked better than it tasted. Mine was a bit dry, and the ingredients didn't work that well together. My friend's dog was deep fried in batter. It tasted better than mine (more saucy), but the veggie sticks on top kept falling off.
I got a combo with a glass bottle pepsi (pretty cool) and fries. The fries was delicious, I saw them cutting fresh potatoes in the back with the pressing machine.
However, the combo came to $15. Pretty pricey for just hotdogs if you think about it, especially for the area.
I don't think I'll go back especially for anything. I don't have a craving for anything particular. We did try their tiny donuts though, it was pretty tasty. Maybe come back for a snack after work?
