Gesture & etiquette

Point to the specific dish on the menu.

Even if they say 'no animal products,' dashi (broth) often contains katsuobushi (bonito flakes) which is fish. Be prepared for this common answer or clarify further if needed (e.g., '魚や肉は入っていますか？' - Sakana ya niku wa haitteimasu ka? - 'Does it contain fish or meat?').
