The ramen is truly excellent here, and well worth waiting in queue outside to get a seat at this super-popular, no-reservations restaurant. The Tonkotsu Black, with roasted garlic oil, adds some exciting spice to a rich base. Service is quick, if impersonal; with so many customers waiting, one cannot really blame the servers for wanting to process the order and send you on your way in record time. I'll be back sometime to try the miso ramen. Only four stars, though, as there are no vegetarian options, which means I can never come here with my partner. I know that authentic ramen is by definition not vegetarian, but it would be nice to have at least one good option on the menu for our herbivorous friends and family.
