You bet! If the venue has a kitchen, and it's open, you can just order off their menu. We find that appetizers are easier than full meals since space is sometimes limited.
We'd recommend that you go early for dinner or stay after for dinner. If you don't have time to do that, then ordering appetizers and finger foods works great while you are painting.
We partner with really great venues and they offer the space for the painting party in the hope of selling you food and beverages so we hope you support them!
If you arrive early and get a table for dinner, just let your server know that you'll be moving to the painting event later.
The ticket price includes the instruction and all the supplies you'll need to recreate your own masterpiece, but no food or beverages are included.
