To keep as one long sentence, you can say "First, you have to visit the Botero Plaza in downtown, and also El Hueco, where you can find everything that you want, including gastronomy as well as many shops and small businesses." The "where" indicates subjunctive clause (attached to immediate noun preceding it, which is "El Hueco" whereas your use of "here" would normally start a new independent clause, causing it to be a run-on sentence).
