How many dishes do they serve a meal?

Please provide me with more context! I need to know what "they" refers to in order to answer your question. For example:

* "They" could be a specific restaurant. In this case, tell me the name of the restaurant.

* "They" could be a specific person or group of people. Tell me who they are.

* "They" could be a specific type of cuisine. Tell me what type of cuisine you're interested in (e.g., Italian, Chinese, etc.).

Once I have more information, I can help you figure out how many dishes they serve in a meal.
