This was the best ramen I've ever eaten. We live in Washington DC and were in Hawaii on vacation. In DC there are a number of acclaimed ramen shops, yet I've always been a bit disappointed. Though usually pretty good, it seems like there isn't one here that lives up to the hype. AGU Ramen definitely does. I had the Spicy Kotteri, my wife and father-in-law had the Chicken Yuzu and my mother-in-law had the Spicy Tonkatsu. All were amazing, though I think I like the Kotteri the best. The flavor was rich and garlicky, though not overpowering. Furthermore, our server Grayson was awesome - my in-laws were unsure about ordering (even my wife and I had a lot of questions, since the menu was different than any place we'd been), and he was super patient and helpful. The service, food and atmosphere were all outstanding!
