Is the tip included in the bill with parties of 8 or more

Usually tip will be added to parties over 6,

No

Nope

Pretty sure, I went with just 1 other person and I did not look at the menu to see about gratuity but it is standard practice in the industry, I have worked in hospitality for over a decade, so just expect to pay gratuity anytime you have 8 or more people, besides, you should always tip your server, 15% for okay service, 20% for good service, gratuity is usually 18% and is not unreasonable for large parties that are going to take more work than a typical table, and takes longer to eat usually, hope this helps
