i'm pretty sure thats the cut we got when we dined at topsiders one evening. it wasn't on their menu but the waiter suggested it and it was great! he told us they always have it, just ask.
this is just to back up the p.p. comment. i think they do offer it, of course, as the waiter told us, if asked. and it may only be at topsiders at dinner, not sure. but its there.
