Middle-Brow, Non-Ethnic in Arcadia
I am fully aware of the amazing food within a stone's throw of Santa Anita racetrack. But I somehow have racetrack friends who don't eat "ethnic" food. (Best not to ask.... consider them "projects").
So: where can I go after a day at the races, to get decent food at reasonable prices with a full bar in Arcadia? The Derby: not an option because of $$ that most of us have lost and a level of decorum when we're all kinda sweaty and smelling of thoroughbred and defeat.
Peppers, across the street, may be the worst Mexican restaurant in California. Rod's is an authentic 50s diner in all the wrong ways.
Surely there's a decent bar 'n' grill nearby? Or a pizza/pasta place where you can get a martini? If so, I haven't found it.
Arcadia is pretty much chain city when it comes to "non-ethnic," once you exclude the Derby.
You might be better off going just a bit west into Pasadena. Robin's BBQ is pretty good, non-threatening and has a full-bar. And it's the sort of place you could go to in the physical state you're anticipating. Or maybe Clearman's - either the Galley or North Woods Inn (the Galley is better if you have a losing day at the track).
Moffett's might be the most "non-ethnic" restaurant in the SGV, let alone Arcadia. I love their signature chicken pies and beef pies. As with Langers, there's a precipitous decline in chow-worthiness the further you stray from their specialty.
EDIT: Just noticed the OP's requirement for full bar. Mea culpa.

We love London Gastropub on Myrtle in Monrovia, which is quite close to the races. They have a new chef and we've tried out most of the offerings. Pub food, burgers, flatbread pizza-ish things, nachos, but all very good fare. They have happy hour as well as we see lots of folks in after a day at Santa Anita. Full bar too.
