I am a big fan of steamboat and have heard about this Da Chang Jin for some time already. But I am pretty surprised what mentioned here differs from what my colleagues told me.

I went on a Wed (18-Mar-09) with 5 of my other colleagues. They offered 2 steamboats "sets" (i.e. the soup and the bbq). I have been to other steamboats where the meat is not marinated at all. But at Da Chang Jin, there are spices and seasoning ( I only managed to recognise basil leaves and chilli powder) available for you to "marinate" your meat. You can leave out certain spices if you do not like it.

They offer free flow of plain water - served in jugs. You have to take the cups and ice yourself. Of course there are other soft drinks available, but there are additional charges.

The range of food is not very wide, though most of the meat products are available (e.g. mutton, pork, beef, fish, crabs, prawns). But the seafood doesnt look very fresh to me though - it look like kinda "mashed up". You gotta add it with the spices.

Other than that there are ready-made dishes like the BimBimBap (Rice dish with vegs and egg), Cold Noodle, Dumpling etc. I personally like the salad (egg/tomatoes/greens/potatoes) a lot.

Service wise, I think it's pretty alright (or perhaps because we went on a weekday). The service staff were prompt in refilling the soup base and replacing the bbq plate.

By the way, I think alfresco is better than sitting indoors - better air. =|

Cleaninless-wise. I didn't experience slippery floors, but my colleagues warned me beforehand not to enter the toilet,
so I went to the one at Bugis instead. =)
