In light of the festivities you've got planned today (that will likely spill into tomorrow), you'll need this weekend to recover.

Which reminds us of that foolproof Japanese hangover remedy: ramen. And we know just where to get it.

Introducing Hapa Ramen, your surefire ramen-filled go-to for bowls of Japan's national comfort food made with a California slow-food twist, setting up their one-day pop-up restaurant this Saturday at Coffee Bar.

Brought to you by Nopa sous-chef Richie Nakano and his bartender compatriot, this ad hoc dinner is a preview of what to expect when they open their brick-and-mortar restaurant. Namely: piles of noodles, and free-flowing drinks to round things out.

Saturday's shindig is going to be walk-in only. And with only 300 precious (meat or vegetarian) bowls of ramen on hand before they run out, you'll want to get there at 6pm sharp and keep the Hitachino flowing.

When your steaming bowl arrives, take a second to appreciate Richie's exacting standards. The broth alone takes four days to reach its delicate and sweet balance of fatty, porky richness. And all assembled—handmade noodles, crispy braised pork, fried chicken and a slow-cooked egg—it's more like a meaty bowl that happens to have noodles.

Since one bowl is just a tease, keep an eye out for Hapa at the Ferry Building's Thursday market next month. Even better, arrange for them to bring their noodle goodness to your office or party.

Then plan your night before strategically.
