Buku takes its name from the international slang for “merci beaucoup”—the French phrase for "thank you very much.” The restaurant's global awareness extends beyond its name to a menu inspired by traditional street food all over the world. Chefs take their cues from culinary traditions from everywhere from Poland to Korea, creating gourmet dishes with authentic international flavors. As a result, the menu's wildly eclectic selection showcases dishes such as thai papaya salad, polish pierogis, and colombian arepas—soft corn pastry stuffed with pulled pork and guacamole.
Regardless of its cultural influence, each meal is prepared using eco-conscious ingredients such as hormone-free beef, sustainable market seafood, and certified-organic coffee raised on a diet of smaller, even more organic coffee beans. Diners can wash down their meals with their choice from an equally international menu of wines and craft beers, along with a selection of cocktails and sake.
