Exact prompt as published in the source.

Find a restaurant suitable for a business lunch near 3100 Travis St, Houston, TX 77006 for next friday at noon.

ChatGPT Used in source Gemini Grok

Sends the Original prompt shown above. ChatGPT and Grok open with it filled in, and ChatGPT may send it straight away. Gemini opens empty, so we copy the prompt for you to paste. Every button also copies it.

Opens in a new tab. We don't see what you send.

Optional stronger version

Our rewrite with extra checks. The poster didn't test it.

Goal: Find and book a quiet, business-appropriate lunch table near [ADDRESS] for [DATE] at noon.

Inputs (fill in or confirm):
- Address ([ADDRESS]) and how far we can walk or drive
- Party size and dietary needs
- Budget per person
- Name and phone for the booking

Rules:
- Shortlist three places within 10 minutes of the address that take reservations and suit a business meeting (quiet, not a bar).
- Check the menu covers dietary needs and the price fits the budget.
- Confirm noon availability for the exact date and party size on the booking page.
- Prefer places with recent reviews mentioning service or business lunches.

Checkpoint: Show the shortlist and wait for my pick before reserving; don't enter card details for deposits without asking.

If you get stuck: If online booking isn't available, give me the phone number and best time to call instead. If a login, CAPTCHA or two-step code appears, stop and ask me to handle it; never guess or store passwords.

Verify before you finish: Check the confirmation shows the right date, time, party size and name.

Output: Shortlist table (name, distance, price, noise level, dietary fit, link), then the confirmation details.

Done when: I have a confirmed table at a suitable place for noon on the right day.

Find and book a restaurant table that fits gluten-free and veggie diets with ChatGPT agentEvidence: Article or interview
Tom's Guide's Alex Hughes asked ChatGPT agent to find and book a table in Bristol for next Wednesday between 7 and 8 pm with vegetarian options at about £30-40 a head. It asked about diets and party size (3 people, one gluten-free) and about two minutes later returned three options, all with tables free at that time and with vegetarian and gluten-free choices, each with an explanation; once he picked one, he only had to add contact details and confirm the booking.
