Frequently asked questions

Can I book servers as well as bartenders?

Yes. Servers clear tables, run a buffet, pass hors d'oeuvres, and keep glasses full. Barbacks work behind the bar restocking, opening bottles, and pouring the simple orders so the line keeps moving.

Will I know who is working my Diamond Bar event?

You will. Staff is assigned roughly two to three weeks ahead, and we introduce your lead bartender by email with their contact details so you can talk to them directly.

How do I pay?

All the major credit cards: Visa, MasterCard, American Express, Discover, and others. For the shopping service you can also pay by ACH transfer, though those funds take longer to clear.

What if my venue is just outside Diamond Bar?

Still fine. We staff the surrounding cities as well. The closest ones to Diamond Bar are Walnut at about 3 miles, Pomona at about 5 miles, and Brea at about 6 miles.

How early does your crew get to the venue?

Roughly an hour ahead of the start time on your quote. Setup covers the bar build, the ice, and the garnish prep, so nothing eats into your first hour with guests.

How far ahead should I book?

Ask for a quote at least two weeks out. Our staff usually gets booked weeks and often months ahead, so earlier is safer, and earlier still in peak season. There is no upper limit either. Book three years out if that is where you are.
