I heard at least 1 moved to Beach Rd, thinking of going there with
some friends some time soon, gathering more info now.
I like the one at selegie, cheap and is most likely the most empty
of all steamboats 
Located along the row of pubs (Liquid Gold and
Plasma)
Liang Seah street does have it's "xian de lai" but kinda pricey
and it's mostly packed... Parklane (as in the noodle shop) does
have a steamboat place in Liang Seah but it's very small, they do
have porridge steamboat and this cute fishcake which looks like a
pig's face...
Clementi has one near sunset place where there's both grill,
sashimi and steamboat (IF i nv remember wrongly) but it's always
full packed and the service is horrible due to the fact it's really
too packed >__> I think AV can provide more info on
this...
I just went to try this Jap grill BBQ at chinatown for like 22
or 24 per pax... Food was ok ok only, problem is, they ran out of
beef after 1 plates... -____- so we stuffed outselves with
pork instead... However they do serve sanma (Mackeral Pike known
for it's fishy smell, some like it, some hate it) ,shishamo, whole
small sotong for grill...
Ultimately the best (IMO) is still the daidomon with the
old price list... 
but alas, the price revision now made it
very un attractive...
Wishlist for BBQ Grill: There's a korean BBQ in east coast which
I heard quite good... Haven go try it yet though...
