Came here with a group of friends (3). If you've never been here before, you have to let one of the workers know that you're waiting for a table. He doesn't write down names but somehow he remembers it all and sits people accordingly. He's a really nice/friendly guy. There's not a lot of seating but turnover is fairly quick.
I ordered the Chosun with spicy level of 4. It was very good. The chicken broth had in-depth flavors. Wasn't too salty. From other chicken broths I've tried at other places in NYC, there is room for improvement. This place can definitely make it in NYC but charging what they charge for the DC area seems slightly overpriced to me. My total without extras was $15.95 after taxes. The hard boiled egg was cooked properly and the yolk was still runny (I assume it's the "ramen egg") so if so, it would be prepared with soy sauce to give it the dark color and Japanese rice cooking wine. The flavors of the egg was balanced, wasn't overly salty. I thought the ramen noodles were cooked perfectly. I didn't get a chance to see the kitchen as I walked by but I don't think they make their own noodles.
Just fyi, their software calculates gratuity at the bottom of the receipt based off of the total (tax + subtotal). Gratuity technically should be based off of the subtotal. You don't pay gratuity on tax. Just a pet peeve of mine. If anything, gratuity is not mandatory, it's just a custom that's been in the US.
I digress, the decor of the place is fairly standard to other ramen places. A nice casual relaxed feel. They accept cc and was able to split the bill easily among 4 people.
I would definitely recommend this place and will be coming back here again to try their other ramens. I will also try their pork buns as it is a staple of most ramen places. I hope they pat attention to detail and add their own flare to it.
