Yes, $12 for a sandwich and side sounds pricey. But the sizes of the servings are deceptive. An arepa and a cup of chili is a full meal. And they were exceptionally good.
The cornmeal "bread" works very well. Firm enough to hold up to the last bite, neither dry and crumbly nor wet and messy. Not as strong a corn flavor as in your average tamale, so the flavor of the filling dominates,
The tray of sauces made for fun experimenting. I didn't consider most of them to be hot, and the one exception was easily tamed, if need be, with the sour cream that comes on the side.
The chili, too, was more about flavors than heat.
I'd say I got my money's worth.
