Fix the number first

Write down the guest count you will actually feed, not the invite list.Venues quote and staff on the fed count. Families routinely plan on the invite list and pay for the difference.
Split the number into ceremony, reception and each pre-wedding function.A 400-guest reception with a 120-guest haldi needs two very different spaces, not one big one.

Space and format

Ask for the seated capacity in your format (round tables or long tables), not the advertised maximum.Advertised capacity is usually floating. Round tables use roughly half again the floor area of long tables for the same headcount.
Ask whether the room can be partitioned or dressed down for your number.A hundred guests in a space built for five hundred reads as a poorly attended wedding no matter the decor.
Confirm two genuinely separate spaces for ceremony and dining, not one room turned around between functions.A turnaround takes about an hour and guests have to be somewhere during it.

Ask what the service ratio is at your headcount and who is on the floor on the day.At a small wedding, attentive service is the actual product you are buying.
Confirm whether a separate pure-vegetarian kitchen is available if your family needs one.
Get the tasting date in writing before you sign.

Check the drive time from Kempegowda International Airport for outstation guests, from the venue itself rather than a map estimate.North Bengaluru venues publish their own drive times; use those and confirm with a test run at your event hour.

Confirm what happens to amplified music at 10 pm and where the after-party moves.Outdoor sound is regulated after 10 pm across Karnataka; the venue should have a rehearsed answer.
Ask who obtains fireworks, baraat and road permissions, and what is excluded from the quote.
Get the venue release time for setup and teardown for each function.
