I actually think Capitol Grille is better than either.
OP, at this moment the coolest late dinner spot in the Twin Cities is Bar La Grassa. Make a reservation, go, and thank me later!
Sorry, I have to strongly disagree.
I have a GC right across 42nd St from me, I've been there dozens of times (as well as Stamford, Vegas, Orlando, Arizona, Chicago...etc). I've also been to Peter Lugers, Sparks (ate right next to Boomer Esiason), Prime Quarter, Ben and Jacks, Rare, Smith and Wollensky, and numerous other steak places in NYC.
None, absolutely none, compare to Mannys. The decor may be lacking (as it is in PLs and others) but the steaks are far better the half dozen times I've been there. Pittsburgh Blue is Ok, a lower priced version of Mannys.
Chain steak places blow, CG is no exception, Darden FTMFL.
Only one that is OK in my book is Texas Roadhouse, especially when you consider everything else (price, peanuts, bread...etc).
