Blue Marlin Diani: Beachfront Seafood, Lobster Mombasa and Menu Prices
Blue Marlin gives a Diani meal a direct connection to the beach: timber furniture, shaded tables and the Indian Ocean immediately beyond the restaurant. Part of Blue Marlin Beach Hotel, the family-operated restaurant says it has served the area since 2008. Its menu gives seafood the leading role while keeping enough pizza, meat and vegetarian choices for a mixed group. That makes it a useful option for a coastal lunch, a date or a family gathering.
A restaurant directly on Diani Beach
The official address is Diani Beach Road, Diani, Kenya. Enquiries and table bookings can be made on 0712 559117 or through reservations@bluemarlinbeachhotel.com. Use the restaurant name when arranging the outing so that the meeting point is clear to everyone travelling separately.
The venue photograph accompanying this guide is published by Blue Marlin itself. It shows the actual beachfront dining area, with wooden tables, shaded seating and a view across the sand. This is the principal attraction for someone choosing between a beach meal and a restaurant elsewhere in Diani: the surroundings remain visible throughout the meal.
The homepage lists dine-in and takeaway service from 8 am to 10 pm daily. Its breakfast menu separately prints a 7:30 am to 10:30 am breakfast period. For an early breakfast, use the restaurant's booking contact to settle the arrival time; for lunch or dinner, the main daily hours provide the broader reference.
What the official menu emphasises
The live main menu was checked on 25 October 2026. The prices below come from that single official page and are in Kenyan shillings. The restaurant highlights Lobster Mombasa, tuna tataki and its sushi offering on the homepage, while the main food list also provides salads, pasta, pizza, grilled dishes and desserts.
That range allows different appetites to sit at the same table. A seafood enthusiast can choose lobster or prawns, another diner can have steak, and someone seeking a vegetable-led meal can start with mezze. Choose the meal's main direction before adding several starters, particularly when planning a long lunch.
Breakfast with a coastal outlook
Breakfast examples include a fruit platter at KSh 800, chia-seed and banana yoghurt oatmeal at KSh 800, and mango-passion-banana waffles at KSh 900. Avocado-and-poached-egg toast and the spinach-and-feta scrambled-egg wrap are also KSh 900. These give a morning meeting several options beyond a large cooked breakfast.
Eggs sunny-side up and a plain omelette are KSh 700 each. The English breakfast is KSh 1,800, as is the shrimp omelette. The difference makes it possible to choose a light start or a more substantial meal without treating every breakfast as one fixed package.
For two people ordering KSh 900 waffles and KSh 900 avocado toast, the food total is KSh 1,800 before drinks. That comparison is useful for a simple morning outing, leaving the rest of the day free for other Diani plans.
Salads and seafood starters
Avocado-and-tomato salad is KSh 1,100, seafood salad KSh 1,800 and ceviche salad KSh 1,600. The seafood version combines several types of seafood with fresh vegetables, while the ceviche uses the day's fish with citrus and chilli. They are different preparations rather than interchangeable lighter mains.
Calamari tempura is KSh 1,600 and king-prawn tempura KSh 2,600. Smoked-fish carpaccio and tuna carpaccio are each KSh 1,800. Fish tartare is KSh 1,600. A table choosing a rich coconut-based main might prefer a fresher starter, while someone wanting a crisp first course can look at the tempura dishes.
A Lebanese set is KSh 1,900, combining several mezze with pita. The smaller Lebanese mezze is KSh 1,000. Eggplant parmigiano is KSh 1,400. Those choices add chickpea, aubergine and cheese preparations to the opening courses, which helps a group avoid ordering seafood at every stage.
Swahili fish and Lobster Mombasa
The signature Swahili fish is KSh 1,800, using coconut cream, vegetables and coriander with rice. Fish fillet à la fresca is also KSh 1,800, with a Mediterranean direction built around tomatoes, olives and capers. A sesame-crusted yellowfin tuna plate is KSh 1,900.
Lobster Mombasa is KSh 4,200. The restaurant describes a coconut, tomato and coriander preparation, making it a specific house dish rather than simply a plain grilled lobster. It is a substantial step up in price from the fish dishes, so the choice should reflect both appetite and the occasion.
Other listed mains include Thai fish at KSh 1,800, fish and chips at KSh 1,800, king prawns at KSh 2,800 and Thai prawn curry at KSh 2,100. Grilled octopus is KSh 2,100 and grilled calamari KSh 2,200. This selection offers different sauces and textures within the seafood theme.
Pizza, meat and alternatives for a group
Margherita pizza is KSh 1,100, vegetable pizza KSh 1,200 and seafood pizza KSh 1,600. Chicken and pepperoni pizzas are each KSh 1,400. A spicy-bean burrito is KSh 1,000, offering a different meat-free route from the salads or mezze.
The meat section lists pepper steak at KSh 3,600, ribeye at KSh 4,800 and kofta kebab at KSh 1,800. Pork belly ribs are KSh 2,900. These dishes matter when organising a meal for friends who like the beach setting but do not all want fish.
Two Swahili fish mains plus a KSh 1,900 Lebanese set total KSh 5,500 in food. Replacing one fish with KSh 4,200 Lobster Mombasa takes that total to KSh 7,900. Those are assembled menu comparisons, with drinks and dessert separate, rather than restaurant packages.
Dessert and a relaxed dinner look
The dessert list includes Basque cheesecake at KSh 1,200, Garash torte at KSh 900 and tiramisu at KSh 1,600. Ice cream is KSh 400 per scoop. Choose a finish after considering how substantial the mains were; a scoop and a full dessert create quite different endings to the meal.
For the outfit, lightweight fabrics and a compact bag suit a coastal dinner. A simple dress, a neat shirt with trousers or an easy tailored set can work without competing with the sea view. Add one focal accessory, such as textured earrings or a small clutch, to make a lunch-to-dinner look feel deliberate.
Moyo Lane's catalogue offers bags and jewellery to explore before the outing. For an anniversary or birthday, a practical accessory can also become part of the gift, chosen for the recipient's usual style as well as that evening's photograph.
