Here are several well-known Mumbai hotels whose restaurants publish or advertise children’s/kids menus (or explicitly list “kids’ meals” as an amenity). I’ve included a source for each so you can check the current menu or confirm availability before you go.

• The St. Regis Mumbai — publishes a dedicated Kids’ / Children’s menu for its restaurants. (fliphtml5.com)
• JW Marriott Mumbai Juhu — the hotel’s dining (e.g., Lotus Cafe / day‑dining outlets) includes a children’s / “Kids’ Special” section on its menus. (fliphtml5.com)
• Taj Mahal Palace, Mumbai (and Taj Lands End properties) — Taj properties advertise children’s menus / kids’ meals among property dining amenities and publish restaurant menus. (taj.tajhotels.com)
• The Oberoi, Mumbai — child‑meal policy and family dining arrangements are documented on the hotel site (meals for children and charges for various ages are specified). (oberoihotels.com)
• Four Seasons Hotel Mumbai — Opus / all‑day dining menus include a Kids’ entrees / kids’ dessert section (hotel dining menus list children’s items). (fourseasons.com)
• ITC Maratha (Mumbai, Sahar) — the hotel’s dining outlets include children’s/kids meal offerings (ITC dining pages and restaurant listings show a kids menu outlet). (itchotels.com)
• Trident (Nariman Point / other Mumbai Trident properties) — Trident lists kid‑friendly dining and family amenities (many Trident restaurants cater to children / list kids’ meals). (tridenthotels.com)

Notes and suggestions

• Menus, hours and menu items can change frequently. I recommend calling the hotel restaurant or checking the hotel’s official dining/menus page to confirm the current kids’ menu and serving hours before you visit.
• If you’d like, I can pull the current kids’ menu PDF or the dinner/lunch menu for any one of these hotels now (and give a short summary of the children’s choices and prices).
