EL TOPO on the top floor of the Eastern is a Mexican place with a great Mexican menu and extensive tequila menu. One of highlights on the cocktail menu are the coconut margaritas which are made with a coconut infused tequila and come with a dessicated coconut rimmed margarita glass.
The coconut margaritas are a welcome treat Ion a hot day. They're not that cheap at $18 but that's standard sydney cocktail prices.
EL TOPO has a small outside area for the smokers - to get there jump in the lift at the Eastern hotel and head all the way up to the roof.
El topo also serves fried crickets if you're feeling game.
