3.5 is the exact mark for the place, because a hot pot remains some thinly sliced chunks of food to dip yourself into boiling water... so there is nothing worth more than 3.5 here...
This being said, compared to some older hot pot places downtown, this is one is almost always busy, thus ingredients taste (are?) really fresh and the place looks much cleaner (at least for now). They also have more than 12 sauces to combine according to your taste, ad lib.
Waiters are OK but do not seem to always understand yes and no. Beware about what may happen if they ask you whether you want more or are done with this or that...
I surely will go back if I am eager for a hot pot downtown. Finally, keep in mind the price... 52 CAD for 2 on a weekday evening for a simple hot pot... this is not of a bargain neither.
