Never been to 575, keep planning on trying it. I still like Tacos Garcia for Mexican (Ross/Osage north of I-40)
Blue Sky (SW corner of I-40 and Western) for hamburgers.
Hoffbrau is a good locally owned steakhouse, on the south side of I-40 between Coulter and Bell.
Don't bother with the Big Texan. To me, it's an average steak at a premium price. Only times I've been there have been with out-of-town guests who bought into the hype.
On the more $$$ end, Kabuki Ramonza is good, it's one of those "cook it in front of you on a grill" places with a neat interior decor. Good for groups. On the north side of I-40 between Coulter and Soncy.
If you're with a group that can't decide where to go, just drive west on I-40, exit Coulter, then stay on the service road toward Soncy. Probably 5-6 chain restaurants there in addition to Kabuki: Saltgrass, Famous Daves, Johnny Carino, Country Barn. And within a block or two of there: Furrs, On the Border, Red Robin, Fazolis, Applebees
If you are in Canyon for any reason:
Sayakorman's SE corner of the square - Thai
Feldmans on north 23rd - "American"
Fat Boys also north 23rd for BBQ
Hil's on south 23rd for Hamburgers (have the onion rings)
Pepitos 23rd just south of main intersection (4th Avenue) - Mexican
