Check a restaurant's walk-in wait time with an AI call

By Jake Marsh Updated 2 min read

Short answer: Tell your agent the restaurant and party size. CallForMe calls, asks the host for the current walk-in wait, whether you can join the waitlist by phone, and when it tends to clear. The call is short, costs $1 if answered, and you decide whether to go before you leave the house.

“Call Kenji Ramen and ask how long the walk-in wait is right now for 2. If they take names by phone, put us down as Rivera.”

Open this in ChatGPT and swap in your details before you send it. It needs the CallForMe plugin.

No-reservation restaurants are great until you're standing outside for an hour. A 40 second call tells you whether to go now, later, or somewhere else.

What your agent does

  1. find_business finds Kenji Ramen, its phone, and whether it's open now.
  2. plan_call keeps the opener short. Hosts are busy, so the checklist is two questions.
  3. place_call dials:
What your agent sends (for developers)
{
  "phone": "+12065550115",
  "business_name": "Kenji Ramen",
  "goal": "Find out the current walk-in wait for a party of 2, and join the waitlist by phone if they allow it.",
  "details": "Party of 2. Name for the list: Rivera. Can arrive in 20 minutes.",
  "questions": ["What is the wait for 2 right now?", "Can we join the waitlist by phone?"],
  "on_behalf_of": "Dani Rivera",
  "callback_number": "+12065550181",
  "constraints": "Keep it brief. Do not agree to a deposit."
}
  1. get_call usually returns ended within one poll.

Example result

Illustrative example: names, prices and times are made up. Transcript excerpt:

Voice agent: Hi, this is an assistant calling for Dani Rivera, on a recorded line. How long is the walk-in wait for 2 right now?

Host: About 45 minutes.

Voice agent: Can they join the waitlist by phone? The name is Rivera, and they can be there in 20 minutes.

Host: Yeah, I'll put Rivera down. We'll text when it's close. What's the number?

Voice agent: 206-555-0181.

Question Answer
Wait for 2 About 45 minutes
Phone waitlist Yes, added as Rivera
Notification Text to 206-555-0181

Tips

  • Put the number you want texts sent to in details or callback_number. The call itself comes from +1 (469) 966-0062, so the host can't text you back on it.
  • Ask for a wait estimate for your exact party size. A 2-top and a 6-top can be very different.
  • Want options? Ask your agent to check three places and pick the shortest wait.
  • Avoid calling right at peak. Hosts juggling a full door are the least likely to stay on the line.

What it costs

$1 per answered call. Checking three places is $3 when each call wraps up within 2 minutes, and any that don't pick up are free.

Questions

Won't a busy host hang up?

Some might. The voice agent keeps it to one or two quick questions and says who it's calling for up front. Calling a few minutes before the rush peaks helps.

Can it check several places at once?

Yes. Your agent can call three nearby spots in parallel and tell you which has the shortest wait.

What if they don't take names by phone?

The voice agent records that, and your agent tells you. Nothing else happens.
