They are famous for their steamboat ('Thai Suki') which is a hot pot with clear stock for you to cook your own choice of ingredients. These may include the basic seafood (prawns, fish, squid etc), meat (chicken paste, chicken slices, beef etc), vegetables, tofu, fisball and meatballs in all sorts of shapes, sizes and colours and some noodles and raw eggs to finish. After cooking all the fresh ingredients, the stocks becomes sweet an flavourful. You must save some ingredients to eat with the noodles and the delicious stock at the end. Slurpy goodness.
So what sets Johhny's apart from our local Ali, Ah Chong and Anand's steamboat places ? Once again - it's in the sauce ! The chilli sauce here, just like the sauce at Coca Thai, is a trade secret and is a true taste of Thailand - sweet, sour, hot and salty all at the same time. I can finish a whole bowl of the sauce on my own with the steamboat. But be prepared with tissue paper as it is suitably pungent, in true Thai tradition.
