Hope Lopez and Heidy Cantoran are making big moves in Dover, in one case literally. The business partners and restaurateurs behind El Azteca opened the Mexican restaurant’s fourth location in Middletown in 2020. Soon, they will be opening their first American-style restaurant, in the state capital. That’s on top of everything else Ms. Cantoran and Mr. Lopez have going on: relocating the original Dover El Azteca to a nearby lakeside spot next year; a rebranding of their company, the Azteca Group; and a deal in the works to license their brand of tequila.
