Guymon eats better than you would expect for its size. The meatpacking plant on the south side of town has, since the 1990s, drawn waves of immigrants from Mexico, Central America, Vietnam, Burma, and East Africa — and the food has come with them. The taco shops along Highway 64 are the equal of anything in a Texas border town; pho is on the menu at several places; there is a Burmese kitchen that has no business being in the Oklahoma Panhandle but is.
For the more traditional Panhandle plate — chicken-fried steak, mashed potatoes, a roll, iced tea by the gallon — try the Yia Yia's-style diners around downtown or the steakhouses on the way out of town. Portions are generous and prices are modest by national standards. Breakfast at any of them is the better meal.
