我点的还没来。

You usually say this to a waiter or the restaurant owner. You can say it while holding the menu or pointing at your empty table. If you want to be extra polite, add 不好意思 (bù hǎo yì si) at the start. That is like saying 'Excuse me' or 'Sorry to bother you'. It keeps the vibe friendly even if you are starving.

Use this when everyone else has their food but you. Use it when you have been waiting more than 20 minutes. It is perfect for busy noodle shops or fancy dinner spots. You can also use it when texting a friend who is bringing you takeout. It is a functional, everyday sentence that gets results.

Do not use this if you just sat down two minutes ago. Chinese kitchens are fast, but they aren't magic! Avoid using it with a very angry tone unless you really want to ruin the mood. Also, do not use it for things that aren't 'ordered'. For example, do not use it if a friend is late to a party.

In China, food is often served as it is ready, not all at once. This means one person might finish their meal before yours even arrives. Because of this, 'checking on the food' (cuī cài) is a national pastime. Waiters are very used to hearing this phrase. It is not considered rude; it is just part of the dining flow.

You can add the specific dish name to be clearer. For example: 我的炒饭还没来 (My fried rice hasn't come yet). If you are in a huge rush, you might say 还没好吗? (Is it not ready yet?). If you are with a group, change 我 (I) to 我们 (we). This makes it feel like a collective hunger strike!
