I wondered if someone could tell me how spicy this is: Fiery Kazan roll - Spicy crab, shrimp, scallops, pickled vegetables and kazan sauce - $19 On a scale of 1-5 (5=so spicy your mouth is on fire!), how would you rate it? Also are the sushi dishes from CA Grill suitable for one person or many people? If you were doing a table of 2 adults, would 2 different sushi plates to share be way too much? Thanks!
