Love of shellfish above all else led the chef of Ubuka to tread the culinary path. He has done his homework, and the results show in a menu filled with crab and prawn suggestions. Some items follow kaiseki style, while others are Western in influence. Terrine of hair crab is an idea borrowed from French cuisine; fried prawns are immersed in sauce américaine. The meal concludes with crab and vegetables on rice cooked in an earthenware pot. Portions are generous to ensure guests can fully appreciate their shellfish. No wonder this restaurant is so busy.
