How is it possible for Mexican food to have zero flavor? I didn't think it was until I went to Zocalo. No cumin, no "middle" notes, just bland red sauce and tons of "smoke"/hickory. If you're lucky you'll get a little bitter cilantro flavor, some high notes of hot pepper, or a little sweetness from the corn chips. No. Flavor.
This is an example of how a place with terrible food will remain open simply because it is in a hot "district" where people go because they think the area is perceived to be safe and fun. (Yet meanwhile loads of better Mom and Pop places off the beaten path struggle because it doesn't cater to the masses...)
Do you find yourself in love with the tableside guacomole? Here's a tip: Go to your grocery store and buy a bowl, two avocadoes, a tomato, an onion, a chile, some cilantro, a lime, and some salt. Use a knife to cut them, a fork to mix them, and invite your friends over to watch it. Some Coronas may help. I guarantee you instant popularity and a coolness factor of 10. You don't need to go here to have it.
The service here is terrible. When I asked the waiter if my colleague could have some more iced tea, he snapped back that he could see her glass was empty, and that he had been serving for over 10 years and that I shouldn't tell him how to do his job. Meanwhile he left our dirty appetizer plates sit in front of us for over 30 minutes.
I have been here four times (dragged by coworkers and friends wanting a "fun" outing) and have hated it every single time.
Don't waste your time or money, Cleveland.
