Most clubs do NOT allow any exact table number from their floor plans / table maps to be selected and secured prior to your party’s arrival.
Your assigned table will be the best available table within the tier you reserved at the time when you arrive; if you want better placement, either you have to A) show up early (i.e. within 30 minutes after the club opens) when there will be more open table inventory in your tier, or B) raise your minimum spend in order to get a specific or preferred table assignment. There are a small handful of clubs that allow you to choose your exact table number (Exchange in LA, Academy in LA, and Time in Orange County).
Ask us if you’re booking a table at any of these venues.
