Espo's has always been one of my favorite spots in Chandler. The exterior is a bit off-putting, but I promise it's well worth the stop. Be prepared to fight for a table inside or to sit on the outside patio as the interior of the restaurant it fairly small. Parking can be a little hectic as the lot is a bit awkward and small.
The service at Espo's is always quick and friendly. You can expect your food to be ready in a matter of minutes. Honestly, you really can't go wrong with anything on the menu. My personal favorites are the tamales, any of the tacos and the enchiladas. The posole is a can't miss when it's available. The portion sizes are great especially when considering the price. Everything is always warm and fresh and absolutely delicious.
Seriously, just go. You won't regret it.
