YamBak is the craft beer bar in Sayulita, open until 3am and something of an institution among people who want to drink well after the restaurants close. The selection runs to local and regional Mexican craft beers alongside imports, with rotating taps that give regulars a reason to keep coming back. It functions as a bar rather than a restaurant, though bar snacks are available.
The atmosphere is relaxed and inclusive — local surfers mix with visiting travellers, and the late hours mean it catches the crowd after everything else has wound down. It's one of the better late-night options in a town that doesn't lack for them, with the advantage of serving something more interesting than mass-market beer.
