Red Fox Grill is my latest lunchtime discovery, as I recently changed jobs and now have to scavenge the P&G end of 4th Street when my stomach growls.
My opinion on Red Fox is fairly split. The prices are fantastic; everything is basically itemized so if you want fries, soup, etc, you can tack that on. You can easily walk out of Red Fox with a $5 lunch, no problem.
The food is really nothing to write home about, but if you're looking for a quickish, down-and-dirty diner lunch, you'll find that at Red Fox. They have plenty of options for burgers and sandwiches, plus some more breakfasty options.
The service is the kind you should expect in a high-churn restaurant like Red Fox: there are two large dining rooms stuffed with people, you see your waitress two or possibly three times total, your food is delivered quickly because everyone is ordering the same things, and you don't stick around to chat afterward. In other words, exactly how a corporate lunch spot outta act.
I say "corporate lunch spot" as Proctor & Gamble is Red Fox's bread and butter. They keep P&Gs holidays, fer chrissake. You'll see plenty of suits and ties in Red Fox; listen closely and you may hear snippets of the future of consumer packaged goods as we know it.
