There's a reason Tiger Den was so heavily mobbed when it first opened. The tiny shop in Chinatown's Dun Huang shopping plaza was one of the first places to actually deliver on the promise of scratch-made tonkotsu pork broth and house-made noodles. Though it has quieted down a bit, owner and chef Mike Tran has made great strides in consistency, delivering authentic Hakata-style thin-noodled ramen in four flavors and at prices that won't break the bank. At its most basic, tonkotsu ramen runs just $8 and comes with three slices of melt-in-your-mouth pork chasu, wood ears, onions, egg and bamboo shoots. The spicy miso, which comes with similar toppings, is fantastic, as is the garlic black bean ramen, ringing in at a mere $9. At those prices, you'll even have plenty of money left over to order a beer or sake, or several appetizers from Tiger Den's robata menu, to make a truly fine meal.
