What, only boys are interested in live fish??[:p]
I think I was confused about Berezka; I was thinking of the Russian store a couple of blocks up from Harvard Street on Beacon. So I haven’t actually been to Berezka. (I’ve been away for quite a while but go back a couple times a year to visit my folks.) Still, it sounds as though other people have.
I’ll second whoever recommended not driving… Boston is not too spread out, foodwise, to do by public transit. The new Charlie Card system is not too newbie-friendly, but the transportation itself is quite good.
