Here are several luxury hotels in Galle District (southern Sri Lanka) that have on-site restaurants — good options if you want both high-end accommodation and dining without leaving the property.

1. Amangalla (Galle Fort) — historic luxury hotel with The Dining Room / Zaal offering elevated Sri Lankan and international cuisine, afternoon tea and private-dining options. (aman.com)

2. Jetwing Lighthouse (Dadella, Galle) — upscale coastal hotel with multiple on-site dining venues including The Cinnamon Room (fine seafood dining), Cardamom Café (24‑hour buffet/casual) and specialty/ signature dining experiences. (jetwinghotels.com)

3. The Fortress Resort & Spa (Koggala) — luxury resort in Koggala (Galle District) with several restaurants (main restaurant "White", seafood-focused "Salty Snapper" and fine-dining "Duo" with a wine cellar). (en.wikipedia.org)

4. Kahanda Kanda (near Koggala) — boutique/luxury hillside retreat with a celebrated Dining Pavilion and dining terrace serving contemporary Sri Lankan and fusion dishes using estate-grown produce. (kkcollection.com)

Notes and tips

• All properties above welcome in-house dining; many also accept non-resident reservations (policies vary). I cited each hotel’s official/authoritative or recent listings above. (aman.com)
• If you want, I can: (a) narrow these to beachfront vs. fort/heritage locations, (b) show distance from Galle Fort or Koggala, or (c) fetch current menus, opening hours and reservation contacts for any specific hotel (I’ll look them up).
