how can they profit?

รสเด็ด (rot det)

honestly, how do you make a profit when you charge the equivalent of $3 for all-you-can-eat?
the best part about this place is the gata, which is a coal-fired pan that has a raised grill in the center and a soup moat that holds whatever kind of soup you decide to make that collects all the meat juices that have run off the grill. take a moment to wipe the drool off your face.

this place has "shrimp" in its name so they have pretty large raw prawns, but they go quick, so keep alive. there's also raw beef, pork, seafoods, chicken, various processed meats (like fish cakes & hot dogs) for the grilling. not high quality meat, but very tasty. for brevity, i will only list some of the other non-grill items: grilled whole fish, pre-grilled pepper steak, raw veggies for the soup, pad thai, spring rolls, siu mai, squid salad, som tam, fried crab rangoon, chicken wings, coconut ice cream, fresh fruit, donuts, muffins, sticky rice and mango, shaved ice with thai sweets. oh yeah, 99B gets you all that and you can stay till they close if you like.
note: it's all outdoors. don't expect an 'A' health code rating.rot det shrimp gata (sign is in thai only). nawamin on the corner of soi 155. (also at sukhumvit 71)
99B per person, all you can eat. if you don't finish too much of what you get, you get charged 20B for every extra 0.1kg. don't load up on the questionable meats.
open from 4pm to midnight, you can stay the whole time if you like.
