Cambodian food leans on rice, fish, coconut milk, lemongrass and herbs. Fish amok, a steamed fish curry, is the national dish, and fish sauce and prahok (fermented fish) appear in many dishes. That means vegetarian food needs a little care: a dish that looks meat-free may still be made with fish sauce or shrimp paste. Say clearly that you eat no meat, fish or egg, and ask staff to confirm sauces.
We found two places with evidence for vegetarian choices. Haven, a training restaurant on Chocolate Road, says its menu has plenty of vegetarian and vegan options. Peace Cafe, near the Old Market, describes its food as vegetarian, though we could not confirm that it is egg-free. We did not find a dedicated Jain restaurant. For Indian food, a guide lists Modiji's near Pub Street as Pure Vegetarian, and Chusska near the Old Market as a halal vegetarian Indian kitchen; confirm egg and onion or garlic with staff. Larger hotels and Indian-run restaurants can often cook simple dishes without onion or garlic if asked in advance, but please check this yourself.
Western-style cafes in the Wat Bo and Old Market areas generally offer salads, fried rice with vegetables, noodles and fruit shakes. Stick to bottled or filtered water, and ask for drinks without ice if you are unsure of the source.
Menus and kitchens change. If you follow a strict diet or have an allergy, confirm with the restaurant before you order.
