On the way from Galle to Unawatuna you can find SEBU Lounge, a new restaurant at the beach with surf vibes. Their vision is not only to bring fresh ingredients to the table but also to create a dining experience. The menu is a good combination between Western and Sri Lankan food, and has lots of veggie and vegan options.
You can easily arrange surf lessons here as this area is well fit for surfers of any level. The waves are very calm which makes it an easy spot for beginners to practice.
