+
+### How much does it cost?
+
+We split the bill amongst the whole group. Usually it's about $15-25 USD per person, tax and tip included.
+
+### I have dietary needs!
+
+[Dim sum](https://en.wikipedia.org/wiki/Dim_sum).js involves sharing a meal with a large group, so we try our best to accommodate you when we order/grab food off carts, and ensure you get first pick of things you can eat.
+
+* We frequently accommodate folks who can't eat dairy, seafood, pork, or nuts.
+* Most restaurants we've visited do **not** have many vegetarian/vegan-friendly dishes.
+* The food at dim sum is **not** friendly to folks who are very sensitive to gluten/wheat cross-contamination, or strictly keep halal or kosher.
+
+But you don't have to eat—join us and drink tea!
 
 ### How do I contact the organizers?
