By rice do you mean Thai foods? Thai foods in some restaurant in Pattaya is the same price as in many Western foods. Just the other day I saw a guy posted 225 baht for a plate of cashew chicken in a restaurant. That means it will cost at least 300 baht including drinks, I would guess. Thai street foods are cheap which I cannot eat. Tried a few times I simply don't like it. My food expenses are never more than 15K baht/month, except breakfast that I make my own. And order lunch and dinner. They are mostly Javanese, Korean, Indian, Mediterranean Burgers, etc. Occasionally pork, or lamb chops. Rice in most lunches. I don't eat steak but sometimes eat carved beef. I like Thai lemon steamed fish and Tom Yum kung.
