We will be in DC for Columbus Day weekend and are looking forward to the great food. We've eaten at Zed's and loved it (it was our first and only Ethiopian restaurant experience) but realize that there seems to be a big debate among CHers between Dukum, Etete, and Zed's - although Zed's seems to be a little lower on this list.. I've looked at both menus online, both look great so how to choose??? And are there any others I'm missing? Give me your best argument for your favorite!
