OK - Milktooth doesn't start its good stuff till 9 am, whereas Love Handle starts at 8 am.
Indy food? Pork Tenderloins, Southern Fried Chicken Indy Style...comes to mind. Perhaps you might be interested in a blast from the past eating in what could pass as one's Great-Grandmother's House --- at Hollyhock Hill, for example, with lace doillys and chicken fried in lard. Or with Hot Water Corn Bread at Mississippi Belle. :-)
Regarding good chains downtown – Oceanaire is actually fairly good for seafood, if not exactly cheap; while Capital Grille is good for steaks and whatnot (with an interesting wine bar next to it in the same hotel at ground level) while you could pig out on protein at Fogo de Chao. But for "old school charm" and a decent Midwest steak and a fierce shrimp cocktail - the local institution St Elmo's might be an idea. But, really, there are many options otherwise, as I also suggested in my PMs, including walking along Mass Ave. but that is a hefty walk from the Westin; while other places around Fletcher Place/Fountain Square are even further away by foot. There are other decent hotel restaurants in the immediate downtown area.
ETA: Embedded in links for various places including localities.
P.s.: If you drive, then any and all of these places become available for exploration, of course - but in some cases parking might be an issue. Cabbing it is an alternative, maybe one way, then a leisurely stroll back.
P.s.2: If you wander over to Mass Ave there are various places to get some fancy cocktails and grab a bite or two. I might be inclined to pop into the (recently relocated) Libertine, myself...
P.s.3: If one wanders over to Fletcher Place (where Milktooth is) I might be inclined myself to head for Bluebeard, but there are various other places there and in Fountain Square, including eclectic and "ethnic" places. There was a recent article from a Noo Yawk-fixated (Brooklyn, actually) reporter on the "scene" there, with rejoinders later from various Mid-West chefs. See here and the subsequent posts for some info...
