Book NowAbout Mahasan
Securing a table at Mahasan takes grit, but carnivores widely treat this Bangkok beef haven as the ultimate endgame. Cuts hit the table sizzling—thick Chateaubriand seared hard over the heat, alongside tender beef tongue finished with rich cured egg yolk. The menu stretches far past standard steakhouse bounds: regulars balance char-grilled oyster blade and ribeye with clay pot rice glistening in rendered beef tallow and bowls of slow-simmered beef tendon soup. Even non-beef eaters get looked after with tender pork options. Service stays remarkably sharp, from quick table greetings to dropped cutlery quietly swapped on clean plates before you notice. Bring two or three friends to split large plates, pay the fair 350 THB corkage fee for your own bottle, and settle in.
- Specialized Steaks: Chateaubriand arrives sizzling and tender, alongside skillfully cooked ribeye and oyster blade cuts.
- Standout Beef Specialties: Tender beef tongue paired with cured egg yolk, comforting tendon soup, and clay pot rice cooked with beef tallow.
- BYOB & Inclusive Menu: Guests can bring their own wine for a modest 350 THB fee, with pork alternatives ready for non-beef eaters.
- Attentive Service: Warm welcomes, proactive menu guidance, and meticulous touches like cutlery swiftly replaced on fresh plates.

Why Dine at Mahasan
Discover why diners consider Mahasan Bangkok's premier destination for specialized beef dining.
Mastery of Specialized Beef Preparations
The kitchen excels in culinary precision across diverse preparations, from tender beef tongue served with cured egg yolk to rich beef tendon soup and specialty cuts like Chateaubriand.
Every dish we ordered was excellent, but the highlights for me were definitely the beef tongue with cured egg yolk, the Chateaubriand, the truffle beef rice, the ribeye steak, the oyster blade steak, and the beef tendon soup.
Lalin C. Exceptional Cooking Execution and Value

Reservations can be quite hard to get, but honestly, it’s well worth the effort.
Tanasit Saikeaw Fulfillment for Meat Lovers
Guests seeking authentic, top-tier beef leave entirely satisfied, recognizing the dining experience as the pinnacle destination for steak enthusiasts.
This place is the end game for meat lover. Definitely a must go if you trying to find real steak.
ZTru BKK Ideal for Small-Group Sharing
Dining in a party of three to four allows guests to comfortably share large-format steaks like Chateaubriand and sample a diverse selection across the menu.
I’d recommend coming in a group of 3–4 people so you can share and try a variety of dishes.
Tanasit Saikeaw Accommodating Group Dining Preferences
Groups can easily dine together without friction thanks to thoughtful non-beef alternatives and a welcoming BYOB corkage policy of 350 THB per bottle.
If you have people in your group who don't eat beef, they also offer delicious pork options. To elevate the meal, you can order wine directly from the restaurant, or you can bring your own—the corkage fee is a very fair 350 THB per bottle.
