Beef Black Burger (B97)

Sounds pretty standard when Casper Burger grills ko khun beef with tomato sauce and Dijon mustard, but what will blow you away are the buns: they’re black. The color is from squid ink, which gives the bap a briny flavor. Or if you’re on strict diet, they also have a pork veggie burger where they substitute the buns with lettuce.
Casper Burger, Mansion 7, 14 Ratchada Rd., 02-275-0952 (delivery is available). Open Sun-Thu 11:30am-midnight, Fri-Sat 11:30-1:30am

Numero Uno Foie Gras Burger (B570)

Keeping in line with their New American cuisine concept, The Garret, boasts an array of burgers, including a foie gras one. In order to maintain their fine-dining reputation, all of their specialty burgers’ signature ingredients are homemade just like their berry salsa that is put together with caramelized onions, balsamic and rocket.
The Garret, Rooftop, Mini Showroom, 99/99 Ekkamai Soi 7, 02-711-6999. Open daily 11:30am-2:30pm and 6pm-midnight

Collagen Burger (from B75)

Burgers have a “bad for you” reputation, so this Japanese franchise wanted to give the guilty pleasure a positive spin—changing the baked buns to steamed, fluffy buns (like Chinese salapao) and mixing in their 5-million-year-old salt imported from Japan with different meat choices. Not nuanced enough for you yet? One of the buns’ ingredients is marine collagen, meant to improve your skin, and they pride themselves on being the first to add it into a burger. Um, congrats?
R Burger, Siam Square, Rama 1 Rd., 02-654-6242. Open daily 10am-11pm

Laab Lamb Burger (B150)

It’s rare to find a spot that’s solely devoted to Thai-inspired burgers. Here, they have types like masaman and green curry. They’ll even give you the seasoned sauce on the side, too, so that you can spice your burger the way you like. The ingredients are also healthier—they use whole-wheat buns—and the patties vary from pork to lamb.
Heawen For Burger Devils, Room Zone A, 2/F, K Village, Sukhumvit Soi 26, 02-661-5052. Open Tue-Sun 11am-10pm

Mean Bean Burger (B225)

This honest American-style diner serving solid burgers has a wide menu selection including some unusual ones. We think their rarest is their veggie burger—a patty made with a mix of spicy black beans and vegetables. Another option a little out of the ordinary but more comforting is their Carbonara Burger (B255), offering a tender beef patty topped with carbonara sauce and cheddar cheese.
Bangkok Burger Company, Unit 103, G/F Opus Bld., 139 Thonglor Soi 10, 02-715-9407. Open daily 11am-11pm

Pork Burger with Namtok Sauce (B250)

Feeling like a burger and namtok? Problem solved. Now you have the all-in-one burger from this new wine bistro. Here, they replace regular buns with their homemade French bread. Moreover, the pork is fermented with Moroccan spices and topped with namtok (Thai herbal spicy salad) sauce.
