The two main eating verbs are 吃 (chī) for solid food and 喝 (hē) for liquids. 我吃饭 means I eat a meal, 喝茶 means drink tea, 喝咖啡 means drink coffee, and 喝水 means drink water. To compliment food, use 好吃 (hǎochī, delicious) or its opposite 难吃 (nánchī, bad-tasting). A common sentence is 这个菜很好吃 (zhège cài hěn hǎochī, this dish is very delicious). For hunger, say 我饿了 (wǒ è le), and for fullness after eating, say 我吃饱了 (wǒ chī bǎo le). Tea is 茶 (chá), water is 水 (shuǐ), coffee is 咖啡 (kāfēi), and noodles are 面条 (miàntiáo).
To say you like something, use 喜欢 (xǐhuan). 我喜欢苹果 means I like apples, and 我喜欢喝咖啡 means I like drinking coffee, where the verb goes between 喜欢 and the object. To negate, say 不喜欢 (bù xǐhuan). To express a learned skill, use 会 (huì), as in 我会说中文 (wǒ huì shuō Zhōngwén, I can speak Chinese). For general ability or permission, use 能 (néng), as in 我现在能走了 (wǒ xiànzài néng zǒu le, I can go now). To order food or drink politely, use 请给我 plus a measure word phrase, as in 请给我一杯茶 (qǐng gěi wǒ yì bēi chá).
Asking prices uses 多少钱 (duōshao qián), as in 这个多少钱 (zhège duōshao qián). The response might include 块 (kuài) for yuan or 毛 (máo) for jiao, like 二十五块 (èrshíwǔ kuài). To ask how something tastes or to describe taste, you can use 怎么样, as in 这个怎么样 (zhège zěnmeyàng). The verb 觉得 (juéde) means to think or feel, as in 我觉得这本书很有意思 (wǒ juéde zhè běn shū hěn yǒu yìsi, I think this book is very interesting), where 有意思 means interesting.
